Great. Xmas dinner at YH's place was as good as you think. The whole place runs like a restaurant.

So, to make it short, it was good. Not a plain Christmas after all.

Watched Dvds til 430 in the morning before leaving the place.

That's Tuesday. Wednesday = Blank.

Thurs. Today, went out with Alicia and Vinvin. Caught the movie MissionSexControl. Somehow, it isn't really .....ah... Hitman is better. Though it was funny at times.

Went back to Woodlands to meet Wai for some bball. Damm ankle. It needs to heal faster!

Nothing much. Same boring life again. Alone.

Tuesday, December 25, 2007

Sunday work, then went to K pool with Ray and Andy until 3am.

Christmas Eve. Dang. Rejuvenating at home. No one asked me out until 1am. So, I took a cab down to Serangoon Garden to meet Jessica, Shi Jie and Robin. We went to Clarke Quay to chill. Ended up in TCC. Had a hazelnut frappe and some spicy pasta that Jessica couldn't finish. Pasta average, but the prawns are delicious. Jessica kinda drank half of my frappe cause it was too spicy.

Didn't do anything much after that, sat at TCC for another 30mins before leaving. Well, ended up at Hougang to wait for the morning bus.

Eve's over. Christmas dinner at Yangheng place later, gonna try out his brother's cooking.

Saturday, December 22, 2007

AH! CRAPPY.

Dammit. The stupid ankle is giving me the chance of slacking! RAH!

Oh well. Bleaching myself for the past few days. It's a nice anime.

Working tomorrow again. Days passed quickly.

See ya.

Wednesday, December 19, 2007

Alright, Time to write some stuffs. Sprained my ankle on Thurs. BBalling with the usual gang and Wai. Kinda careless with that game.

And so, couldn't do quite some stuffs for the next few days til Sunday, which I went to work. Aki came to meet me after work, was planning for a movie but scrapped that idea cause it was too late. Then we went to play a game at Raiders, after which I sent her home and then took a cab home. Yeah, it was quite late, cause we talked abit.

Monday = Slack. Tues = Work. Ray went down with MC again. Nasty food poisoning.

Anyway, boredom. Been watching Bleach. AH. Ok. Tiring but can't stop.

Shall continue watching. Ciaos.

Thank you for taking the Creativity Test. The results show your brain dominance as being:
Left Brain 36%
Right Brain 64%

You are more right-brained than left-brained. The right side of your brain controls the left side of your body. In addition to being known as right-brained, you are also known as a creative thinker who uses feeling and intuition to gather information. You retain this information through the use of images and patterns. You are able to visualize the "whole" picture first, and then work backwards to put the pieces together to create the "whole" picture. Your thought process can appear quite illogical and meandering. The problem-solving techniques that you use involve free association, which is often very innovative and creative. The routes taken to arrive at your conclusions are completely opposite to what a left-brained person would be accustomed. You probably find it easy to express yourself using art, dance, or music. Some occupations usually held by a right-brained person are forest ranger, athlete, beautician, actor/actress, craftsman, and artist.

Wednesday, December 12, 2007

Alright. Tuesday. I actually missed out on today's Hougang bball. Sorry Jess.

Anyway, I think I failed my test today. So, oh well. Then I was supposed to study and stuffs, but I went to catch a movie with Aki.

Grabbed a bite, a big one, at PS Kopitiam, after we got the tickets for Hitman. Then played the bball machine at PS arcade, it was so easy. But I couldn't be bothered to play much, and the show was starting.

Hitman. Great show. Aki was abit slow with the plot. She kept asking me. LoL. Ok. Nudity in the NC16 show. Other than that, the plot is really packed with actions and fast paced. I would definitely watch the sequel if there's one.

Sent Aki to her block and chatted for around an hour. Then my dad came to fetch me. =P They guessed my break-up with Yaling. Haha. Kinda slow, but at least they noticed. My mom was like "Hmm Good Good". Ok. What the heck.

Got home, and Caryn asked me out for a run. 12am. OK. ON! We ran approx. 3km after which I couldn't stand it anymore. Alright, she beat me. Fine. Then we played some bball til around 1am.

Blogging after arguing with polar dude. Deep misunderstanding I guess. Can't we even have a proper arguement?

Time 1:48am. Time to go. Bye.

Tuesday, December 11, 2007

Why do I still feel so empty when I'm supposed to be so busy?

LoL. Tough Life eh.

I already forgot how to key in her number when I sms. Reminiscing. Stuffs.

Caryn told me I need to have an aim in life, so that I won't feel empty.

Aim?

Sigh, Signing off. Morning.

Monday, December 10, 2007

Alright, I was kinda busy for Sat & Sun. Well, maybe Friday too.

I went to collect my pay on Friday at AMK V.Hive. Then I met Ray there, well, I stayed there and chatted abit. Kinda bored as there wasn't much sales that day. The pay seems messed up, so I took awhile too. And, met Ken from GreatWorldCity V.Hive.

Ray and me kinda had a bet to see who will finish what the other treated to drink first. He got me a Guiness Stout, and I got him a Tonic. LoL. He lost miserably. =P lol. $3 stout for 60cents Tonic. What a rip off! Oh well, it was a challenge, and I know he can take alcohol. So yeah.

We went to walk around, got dinner for Ken, [ We are not gays.] then we returned to the outlet and chat abit again. They kept calling me to slit my wrist whenever I complained that I'm bored or sian. Dumbass. And lots of gossiping crap, after which he treat me to a can of Heineken, and another Guiness, followed by more gossips. Then another Heineken after closing. I think I was already tipsy.

Went home around 12 and fell asleep til 2.30am. Uh. Probably due to the beers. Woke up due to my sms alert. Oh Aki. Fell asleep again after that, and woke up at 8am. Somehow, I was late for work at 10am. LoL.

Work was boring as usal. Saw Fly at IMM. LoL. He was selling cameras. Then there was this Xing Guang Shi Shao PK crap there. I remembered some banshee froze me with her ghastly high pitch. But others were rather good. Met Fly on the train back home too. Quite a concidence as he was supposed to finish work an hour earlier than me. Chatted and stuffs.

Home. Msn, shower, slept. Nice. Sunday. Work. Late. Crap. Crap talk with Jayson. Work. Work. Boring. Smsing Aki. Crap talk. Crap with customers. Annoy them. Annoy myself. The last customer really got me irritated, nearly screamed at her. Geez. Ray came down during closing. LoL. More crap talk.

Home. Msn, sms. shower, ate, msn, then blogged all these craps. I wonder who will read all these craps. =P

Alright. Bye.

Sunday, December 09, 2007

Busy. -_-" or rather ..... life less. Life is boring!

LoL, maybe I should cut my wrist. =P

Be back later.

Wednesday, December 05, 2007

Alright. Wednesday.

I think I gonna make Wednesday as my break day.

Tuesday was a hell lots of fun. I went to met Jessica at Eunos at around 6pm, then we get down to Hougang for BBall. Familiar faces, cool. Then, we started playing 4v4. There's Lawrence, Nicholas, Jessica and me on our team. We kept winning, continously for around 5 rounds of 7 points.

Lawrence has some gay (powerful/cool) moves, Nicholas has good rebounds and close-range shots, Jessica did quite alot of great "center" moves and a couple of far shots. Well, I.. just played around with Nicholas backing me up. Cool. Law and Jess did some great passes, but somehow my reaction isn't fast enough. Anticipation isn't there.

It is really fun and all. It is not about my personal skill anymore. I really appreciate good team mates that moves, attacks, defends and apologise if a mistake is made.

If you really think you aren't good enough, do something about it. Improve and not rely on others. Even I myself need improvement. Though I always gauge whether my teammates are reliable, I know I'm not good enough. Be strong and stand on your own.

Alright, after the games, we went to have dinner at a nearby coffeeshop. Jessica and I shared Niang Miah..Whatever it is spelled. =/ Oh yeah, there was Guo Xiang, Joel, James, eh.. ahh can't remember. Some auntie keep forgetting one of their order. So he went without dinner. LOL.

On the way home, Caryn called me telling me she's restless, so I went to met her and played bball again. at 12am. =/ Wow. Restless. Played abit of bball, went to her house for a shower and talked abit til 3am. Filled up the gaps where I didn't contact her since everyone grad. Guess alot of friendships ended too. LOL

Wednesday -
Morning practical exam, then did powerpoint presentation for MEMs as well as the report. I was frigging sleepy. Then MEMs lesson for presentation, which I think I did erm. Badly. =P I'm still a bad presentor. Stage-fright I guess. After that I went home and rest.

I woke up at 10pm. My entire house was in darkness. LOL. Completed the escape game which I played awhile before sleeping earlier. Watched abit of animes on Central then I came in to blog and chat.

It is now 230am Thursday. Talked with Yaqing about Yaling. Some stuffs that will make me a bit upset but also stuffs that I wanna know.

Alright, that's all. Bye =

Monday, December 03, 2007

Alright, went to Leo's bbq after work. Haha, asked Jessica to come along, and she brought Yuan along. I kinda forget about this guy. It had been so long since I saw him, or actually think who is he. Nevertheless, I don't mind getting to know more friends.

Jessica is.. mmm. a great person to have at a bbq. Let her do all those cooking! lol. Experiences beat everything. Eating, playing, talking.. LoL. I don't even know what to blog. Didn't get to sleep, played cards til 530 then sent Jess and Yuan off before going to shower. Slept for an hour before leaving for work. LoL.

Very tired, but I love my colleague. He let me rest, in the storeroom. Slept for like 20% of my time there. Sales wasn't that bad today, sweet, more money. I was too tired to even try to starve myself today. Somehow, I am too heaty today. Kept having nose bleed.

Thanks Polar, KS, JW for coming down to AMK to gather today. LoL. Thought you guys will just go out and chill without me, but you guys came for me. Sweet. What are friends for? Haha, had chicken rice after work. It is delicious. Superb soup that came with it.

Somehow, they are worried that I got dengue again. lol. Nose bleeding? Thanks for the concern. I think I will be fine tomorrow.

-I met someone in the morning. Weirdly, he claimed to know me. He told me I will be fine and I should go dutch. It is weird, but I will remember him. =)

Friday, November 30, 2007

Guess I had done abit of work for that project. Did I mention abit?

Sigh, I guess polar is still angry with me. But what can I do? Both are my good friends, and I certainly know that what he did was wrong. Even for leo. Still, they are my best buddies. Maybe as buddies, I should had let them know. Corwardy me.

Hope this incident didn't hurt our friendships. Worse for me being in the middle of it. =/

Today was quite rejuvenating for me. Waking up, sleeping, waking up. It's so peaceful. Moreover the whole room is so clean. I feel so good.

Alright, couple of friends asking me to go out tomorrow and stuffs.. but I'm working. Sigh. Have to reject them. Or, do some special arrangement for them. I can give up my lunch break to walk around with them if they want.

Leo's BBQ tomorrow, perhaps I can arrange to go after work. Need to ask him then. Maybe I will stay there overnight, and then report to work the next day after showering there. More plannings needed. Luckily I got 2 set of uniforms. Ha.

Guys, I really want to gather with all of you, but I need to work too. So sorry. Perhaps on weekdays? I know you guys are busy too. So yeah.
My arms are aching badly. =/ great. over-usage of my tricep muscle. Basketball, Push-ups. I think the push-ups are the killers. Sigh.

Nevertheless, I tried. Hopefully, I can get some result by the end of the year. I'm hoping to drop back to 75 kg. Haha, I'm trying.

2pm now, I still owe Alicia the report. =P But I got bored and came blogging. Alright, going back to report. Maybe I will come and edit this post later.

Oh yeah, Canon rock sounds great.
Ah.. Did some housekeeping. Well.. at 2am. It's already 4am now, but I'm really happy to be in a clean room.

It feels... much... ........... cleaner. =)

Wahaha, but still kinda weird to do it at such time. And at the expense of not doing Alicia's project. =/ Not really good. Alright. First thing tomorrow will be rushing out that frigging report.

I'm trying to get my life back on track. Being going out with Jessica to play basketball. I really love it. Why did I left it in the first place? Sigh. Maybe I should start searching for people who love it as much as me to play with me. My usual group of friends. Sigh. Please play with me leh? I don't want to neglect you guys. =/

I wonder if you guys are thinking that I'm wooing someone. Actually, I'm not. I'm just trying to enjoy my life. I had wasted enough. I used to envy. Envy people who know this.. know that, but never actually going down to learning it myself. Pretty pathetic. Actually I love how a guitar sounds too. But I'm not really into Heavy Metal, or.. what ever Led Zeppelin that you told me about. Perhaps I never listen enough. But it is not justified for you guys to say I suck.

Hope you get what I mean. I would never say you guys suck when I know something that you don't, so I don't really appreciate that gesture.

So sorry, Alicia for that little big incident. My friends were being insensitive. Me too. Sigh. Thanks for actually pointing out my flaw.

Alright. almost 430am now. Time to get some sleep. Perhaps I will be playing badminton with Alicia, Vin, Hao tomorrow. LoL.

Bye.

退后

天空灰得像哭过
离开你以后
並沒有更自由
酸酸的空氣
嗅出我们的距离
.
一幕锥心的结局
像呼吸般无法停息
抽屉泛黄的日记
榨乾了回憶
那笑容是夏季
.
你我的过去
被順時針的忘记
缺氧过后的爱情
粗心的眼泪是多余
.
我知道你我都没有错
只是忘了怎么退后
信誓旦旦给了承诺
却被时间扑了空
.
我知道我们都没有错
只是放手会比较好过
.
最美的爱情回忆里待續

Saturday, November 24, 2007

Alright, just got back from work. LoL. Cool boring stuffs at work. =] Dammit. Doing sales is crappy with sales.

Anyway, still thinking of her. Gosh. =/ But still ogling at girls during work today. So many pretty faces and hot bods. What am I supposed to do? =P

So darn bored. Anyway, met up with polar after work. Ok, didn't do anything but... lol. Meet for fun lor, nice to crap abit now and then.

And, so many things to do with my friends too. Like meeting up with Jessica to play basketball sometime soon. Bringing Alicia to see some sofas at V.Hive. Erm.. and.. can't remember. LoL. Now I have all the time in my world, need to plan it. =)

Oh yeah, I didn't mention that I'm working at V.Hive furniture shop, did I? Haha, come find me if you need a new wardrobe, bed or a boyfriend. =P

Ciaoss

Thursday, November 22, 2007

Haha, She just told me to go meet her someday to get back my clothings that are left over at her place. And She isn't home too. Out with her new bf. Somehow, this didn't get me angry. Finally put myself at ease.

Was confused for a moment. Wanted to go back to ask her like I did the other time with Jasmine. Perhaps I did wrongly the other time. It was obvious. I worried too much. I should had been more .... suave...[ is it the right word to use] when dealing with matters of heart.

It had always been like this. I can always tell my friends to break up when I know that something is wrong between them. But I couldn't do it myself. I'm reluctant. I'm worried that I might hurt them. I want to take up responsiblity even though I know I couldn't do it.

Perhaps I'm wrong all along. I'm not being emo about it. Finally found someone who I can talk this with. He managed to open my mind. And I believed. I know I'm not good enough. And I need more confidence.

Ok. Wait. I didn't mean He. LoooL. Not God for Heaven's sake. =P

Sidetracked. -_-"

=) Finally at ease. My heart isn't swaying.

Metamorphosis.
Oh, currently sitting outside of the tutorial room waiting for my friend

I'm bored. lol. Forgot to bring my hp again today. Geez. Crappy memories. Anyway I was trying to reach for my ring on my middle finger today without me realising it. Ha.. My body still haven't get use to the break up. =P

Like how I'm not used to wearing watches. Still wearing the Levis watch she gifted me.

Wednesday, November 21, 2007

O.O Surprised that you still remember me. =) Nevertheless, nice to "see" you again, after so long. Fuzzy memories came back, haha thanks for reminding me. Guessed I forget to remember the good times more than the bad. No wonder I'm so emo.

Ok. Emo isn't such a good word to use. LoL.

http://www.urbandictionary.com/define.php?term=emo

Pretty funny explaination and well, I didn't know it's a type of music. LoL

Starting to feel better already. Still think of her now and then, but she has the right to choose anyway. I will just stand back like I had always been.

I can also use the time to concentrate more on my studies, though not that useful now. -_- regret thinking that grades don't matter til the final years. How immature. I can also concentrate on getting myself back to working order. LoL

Body been malfunctioning. I mean.... I can't even run 1 km without sweating? This is not me, and I had been blaming it alot on life. LoL Emo syndrome. Have to make it work myself.

Retarded Polardevil today tempted me off Judo today. =] lol, ton a night over at his place, am tired anyway. Perhaps will go for a game of bball, with my bro. Gundam Jeremy. =) LOOOOOOOL

Thanks Jasmine for dropping by, leave more comments when you do again. This is a lonely emo blog. =P

Ciaos

Tuesday, November 20, 2007

Why am I contradicting myself? Whenever I say not to think of her, I would be thinking of her at the moment I write this down, and it will be with me for the next hour.

Is this reliance or love? I couldn't differentiate it anymore. Integrate it then. =/ Jokes. Trying to make myself smile, it works when I'm with peeps. Trying to be funny. Trying to forget. Trying to change.

Still, I feel the same emptiness. And everything will be over when I stop writing about her on here. Somehow, I don't want it to go that way. But, I couldn't give myself a definite answer.

EMO.

Putting it away, it is me who you see. I guess no one was able to read me at all.
-----------------------------------

I went for class miraclously... is that right... on time. LoL Was expecting Mr Vinnp, as I rmb him saying he would be taking us. But it's ok, I don't hate LK. Just abit full of himself when he explains stuffs. Time passed quickly, and after that I met up with Polar.

Went back together, had lunch at Pastemania. Went to find a bag. Failed. Went to timezone for some gaming. Boring. I really hate timezone for limiting their bball machine to only 4 balls. I have to wait so long for the ball to roll back. = = Few games of pinball then I left for a haircut. Polar went home with my bag first. Went there after my haircut for some gaming fun. Leo came. Sweet. Dad and Mom asked me to go down for dinner and then I'm here after settling my private stuffs.

LoL, I have to post something normal. =)

Alright.. Ciaos

Monday, November 19, 2007

I'm feeling better now. At least I think so. Had a new haircut. ZOMG dorky. Sigh. Really not suitable for my FAT build now. Trying not to think so much about her, but every now and then, I would be feeling my middle finger for the ring that I had wore for so long.

Anyway, went to look for a nice backpack today. but, sigh.. I think I'm too fat for any backpack to look nice on me. Really dont wanna use a sling bag, cause it stinks my chest. =D

Sigh. Alright. Signing off.

Saturday, November 17, 2007

Broke up on the 15th. Talked through it with her though she is the one who suggested it.

Well, its the 17th now, didn't sms once or call. I should let it go then. I wonder why am I still worrying about her. She got 2 other guys actively on her tail, and she is out with them late at night at the arcade when she is supposed to be having a curfew. Alright, let it go Oblivious. It is for her, to let her become happier cause you couldn't do it. Just hope she won't do anything foolish.

Oblivious. Have I mentioned about metamorphosis? Planning to use it as my new nick/motto. Oblivious. Yeah, I really need the metamorphosis. Couldn't be the same anymore.

Had not told alot of my friends or even my family about it. Maybe there isn't a need to. But it feels weird when my friends ask me why she didn't come, or didn't follow me.. or anything related with her. Guess I really spent alot of time with her without me noticing it. I lied to them that she's working. And I didn't expect her to be outside at arcade when I call her at 10pm. I feel bitter. Wanted to send her a sms full of sarcasm, wishing her happiness with her new life.

But, alright.. I'm not that much of a loser. It hurts knowing that my 17 mths relationship is really over. I need to adapt again. I really don't hope to get into a relationship again too soon. I'm certain that I would not be able to do much for "her", empty promises, fading love. After that it will end again.

If I really love her enough, I wouldn't had let her go.

For the last time,
Yaya.. I loved you.

Thursday, November 15, 2007

Having some changes now. Am I emo? geez. Oh well, my temper isn't really good nowadays. Awfully bad. To someone. I wonder why. Sigh.

Im teh lozer.

Monday, November 12, 2007

Metamorphsis

Well, done fixing my tagboard, AGAIN. Dying due to in activeness...well, can't anyone of you help me do that? And I see my report still on the previous entry. Had to do that due to hotmail's timely break down in service.. - -? Gonna remove it soon, if not.. I think the other BME studs will start finding my blog due to google search on their next reports. Cool Eh? =)

Start working again nowadays, Cool. Having a income again, which means I can buy more stuffs...... for myself hopefully. Lawl. Why m I blogging... oh yea, gonna find a new skin.. or make one.. if I wanna learn that is... HTML SUCKS! cause I'm bitter that I don't know. It applies for Guitar Heros, Drummania, DDR and Keyboardmania. =P Bah!

Keeping myself busy is better than feeling lost. Working rocks. Game sucks, but got to know a new girl. ZOMG. Cousin of friend, what a small Earth... or.. Virtual world?

Abstract

Non-conventional MEMs Processes

Micro-stereo lithography

Micro-stereo lithography (mSL) has been developed to produce highly precise, three-dimensional (3D) microstructures from broad selection of functional materials, especially biocompatible materials. In principle, mSL utilizes focused light to scan over the surface of a photo-curable resin, which undergoes photo-polymerization and forms solid microstructures. The mSL fabricated devices, containing complex engineered microstructures which are covered with self-assembled functional groups, can work as a unique interface between the nanometer scale functional group and Marco-scale bio-medical samples, therefore can find applications in Bio-MEMS.

The MSL system and the principle of operation

.

Sol-gel Coating

The sol-gel process is a wet-chemical technique for the fabrication of materials starting from a chemical solution that reacts to produce colloidal particles (sol). Typical precursors are metal alkoxides and metal chlorides, which undergo hydrolysis and poly-condensation reactions to form a colloid, a system composed of solid particles (size ranging from 1 nm to 1 μm) dispersed in a solvent. The sol then form an inorganic network containing a liquid phase (gel). Formation of a metal oxide involves connecting the metal centers with oxo (M-O-M) or hydroxo (M-OH-M) bridges, therefore generating metal-oxo or metal-hydroxo polymers in solution. Drying process serves to remove the liquid phase from the gel thus forming a porous material, then a thermal treatment may be performed in order to favor further polycondensation and enhance mechanical properties.

The applications for sol gel-derived products are numerous. One of the largest application areas is thin film, which can be produced on a piece of substrate by spin-coating or dip-coating. Other methods include spraying, electrophoresis, inkjet printing or roll coating. Optical coatings, protective and decorative coatings, and electro-optic components can be applied to glass, metal and other types of substrates with these methods.

Cast into a mold, and with further drying and heat-treatment, dense ceramic or glass articles with novel properties can be formed that cannot be created by any other method.

Nanoimprint lithography

It is a novel method of fabricating nanometer scale patterns. It is a simple process with low cost, high throughput and high resolution. It creates patterns by mechanical deformation of imprint resist and subsequent processes. The imprint resist is typically a monomer or polymer formulation that is cured by heat or UV light during the imprinting. Adhesion between the resist and the template is controlled to allow proper release.

Thermoplastic nanoimprint lithography

Thermoplastic Nanoimprint lithography (T-NIL) is the earliest nanoimprint lithography developed by Professor Stephen Y. Chou's group. In a standard T-NIL process, a thin layer of imprint resist (thermoplastic polymer) is spin coated onto the sample substrate. Then the mold, which has predefined topological patterns, is brought into contact with the sample and they are pressed together under certain pressure. When heated up above the glass transition temperature of the polymer, the pattern on the mold is pressed into the melt polymer film. After being cooled down, the mold is separated from the sample and the pattern resist is left on the substrate. A pattern transfer process (Reactive Ion Etching, normally) can be used to transfer the pattern in the resist to the underneath substrate.

Photo nanoimprint lithography

In Photo Nanoimprint Lithography (P-NIL), a photo(UV) curable liquid resist is applied to the sample substrate and the mold is normally made of transparent material like fused silica. After the mold and the substrate are pressed together, the resist is cured in UV light and becomes solid. After mold separation, a similar pattern transfer process can be used to transfer the pattern in resist onto the underneath material.

Electrochemical nanoimprinting

Electrochemical nanoimprinting can be achieved using a stamp made from a superionic conductor such as silver sulfide. When the stamp is contacted with metal, electrochemical etching can be carried out with an applied voltage. The electrochemical reaction generates metal ions which move from the original film into the stamp. Eventually all the metal is removed and the complementary stamp pattern is transferred to the remaining metal.

Laser Micro machining

Laser micro machining provides non-contact machining of very high resolution, repeatability and aspect ratios and can be fully automated

It can be controlled to do localized heating and requires minimal re-deposition.

The product normally requires no pre/post processing of material and could be done in a wide range of materials: fragile, ultra-thin and highly reflective surfaces

Ultra fast or Long

Ultra fast means that the laser pulse has a duration that is somewhat less that about 10 Pico seconds - usually some fraction of a Pico second (femtosecond). "Long" means that the pulse is longer than about 10 Pico seconds, that is, longer than the heat-diffusion time. These long pulse lasers may be continuous, quasi-continuous, or Q-switched, but in any case they are generating long pulses compared to the heat-diffusion time.

Laser Micromachining of Silicon: Fabricating THz Imaging Arrays

During fabrication of THz imaging arrays using laser micro machining of Silicon, the silicon substrate is contained in a flat vacuum cell under a slowly flowing ambient of chlorine. The thermal micro reactions of silicon in chlorine are chosen because of their speed. The chlorine ambient reacts with the silicon at temperatures near the melting point to form volatile silicon chlorides, which are pumped away from the surface . A ~1 micron3 of silicon is brought to just above its melting point by a focused, CW argon-ion laser operating at 488 nm wavelength. The (circularly polarized) beam is deflected in the x,y plane with a pair of computer-controlled galvos. A field size of 256 x 256 pixel elements can be addressed in random access speeds up to 5 x 104 pixels/s, or in a raster mode up to 2.5 x 106 pixels/s. The chlorine gas pressure, laser power, and scan rate are adjusted to give optimum surface quality. Waveguide surface roughness values measured with atomic force microscopy are typically on the order of 200 nm RMS. This surface quality is already sufficient to provide low-loss waveguide performance to > 10 THz. The RMS surface roughness can be reduced even further, to under 25 nm using standard polishing etch solutions. When necessary, multiple fields are stitched using a 4 inch travel x,y stage driven with stepper motors. Once the micromaching process is completed, gold is sputtered on the micromachined structure to make it conducting.

Laser bonding/Welding

The process involves using an interlayer of a mixture of two materials and reacting the materials with laser irradiation to form a thermally stable compound suitable for bonding the bodies together.

During LB process, a focused laser beam is transmitted through a transparent glass wafer and absorbed by the surface of an opaque silicon wafer. The absorbed laser energy melts a thin layer of the opaque substrate as well as the transparent material near the interface. This melting results in the formation of a strong chemical bond. In the present study, a LB workstation with the necessary apparatus was developed for experimentally establishing the correlation of the bonding process and its material parameters with the resulting quality of the bond. The parameters of contact pressure, surface roughness, the thickness of the intermediate oxide layer and bonding geometry were examined for their influence on the bond strength. The typical bond strength achieved by LB technique is 10 MPa. This strength, as measured by a tensile test, is comparable to the strength of bonds obtained using other major wafer bonding techniques including fusion bonding and anodic bonding. The bonded interfaces were analyzed using Auger electron spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS) to define the mechanism of the wafer bonding through evaluation of the migration and diffusion of different atoms among the glass and silicon substrates during the bonding process. The main advantage of using the LB technique is that the bonding process can be performed at room temperature with a relatively low contact pressure and a reduced bonding time. There is also no need of applying a high electrical potential. TLB can be easily integrated into an existing semiconductor production line without adding a vacuum environment.

I'm feeling lost.

Ask me what I wanna do? What I wanna be?

I don't know. I really don't know. Just feel like idling the rest of my life away.

Nothing really interests me anymore.

I have no aim. From a long time ago? Now no motivation. No drive. No feeling. I'm indeed turning oblivious.

How much do I care?

Looking for a job. xD Anyone recommend me?

Tuesday, June 05, 2007

Happy Birthday Polar. Lol. Wow.. first thing I said after being away from blog for so so long.. Just nice eh? I couldnt remember until he said it. Sigh. I dont even remember my parents birthday, I have to be fair right?

Sigh. I think I love myself more than anything else. Selfish me. Why am I even saying this? Is there any links? LoL. W00t. The self reflection blog. AKA talking-to-self blog.

AH.. I forget what I wanted to write the past few days, as again I procrastinated and often sinking in my inferiority complex. W00t.

Inferiority complex due to my looks, weight, hair loss. Ahh... all belongs to the 'looks' category.

Why is it that I think I'm spending too much time with my gf that I don't have much of my own? Is it just me? I want freedom? Independance Day! Nah.. I just hope my gf could be more independent. Read some old mag lying around my bed. (ya my bed) Some articles about how girls can keep guys commited. Blablabla...

Cant blame her too. xD Im not Mr Nice guy anyway. Hahahahaha. I feel like exercising evryday, but I end school ard 6 everyday. She will be expecting me to go home to play game with her, or go her house to play with her, as well as watching 9pm serial.

To be serious, my eating habit remain pretty much the same, but I used to play basketball 24/7 even when I had have a gf. Ask polar. He knows, or at least his sister knows. Yea yea.. I'm still as selfish as ever. Fun more important than everything else eh?

Ok, back to myself.. I think love is so... LoL. To make me think I love you? Simple. Just break my heart and I will know. If not, I won't. If I feel nothing when you try, means.. you know. <-- this paragraph sucks.

I'm so bored with school. So boring. I keep saying to myself that, if I wanna study, no one can beat me. But I think this killed me. I really sucks now. Studies.. sigh. Just getting bad to worse. Why cant things be as interesting as when I'm still young.. like primary school? Is my self complanace (com-play-cent..WHATEVER) growing out of proportion of my real abilities? Or m I just lazy...? Skikamaru rocks, but he's a genius. I'm just slight abv avg in IQ. Polar isnt doing too well himself already. (His IQ higher than mine...as much as his fats =X [the difference is getting lesser {hey,this means im getting cleverer??}]) =D

Alright. Be back later. (the word 'later' works wonder, as there isnt a limit, unlike 'tomorrow')

Some time since I blogged.

Yaya broke her collar bone this wednesday during a rehearsal which she wasnt in the first place. I noticed her during the front part of the rehearsal, maybe I should had stopped her. But I didnt know such things could happen.

She in great pains this few days, as TTS wanted her to wait for a week til she can see a specialist. Her condition of the bone isnt that good already, why cant the hospital arrange the appointment some what earlier? So she do not need to go thru the pain and popping of useless painkillers. Maybe SGH could gave a better service.

Anyway, she is emotionly unstable this days. Regrets, and keep thinking that she is a disabled person now.. and that she will nv recover or last the 7 days of waiting. I do not know how to console her. Just hope that being around with her will make her feel better. 5 more days to go, hope everything will be fine. Muack Yaya, Jia you! =)

Back here again. Used to only come here when Im sad and depressed. Thus, feels abit weird that Im blogging now.

Actually Cant really remember what I had wanted to write a few days ago.

Went polar house to bai nian. The last day to get hong bao. YEAH~ It wasn't really fun, but still I enjoyed the friends' company. =) Sigh, once a year. Maybe not that long, but it's really hard to meet up. Well, at least for someone like me. Yeah, I can't be bothered to go organize all those stuffs. Not that I don't like, it is just that my irregular planning would probably end up in a bad plan anyway. =P

Oh! Xinyi and Subi got together. Shocked. >< Quite lar. Maybe I just don't know what type of guys Xinyi like, that's why I had feel abit shocked. Jason, was abit too. As long as she's happy bah. I have no rights to say anyone else.

Vexed. =) Seems to be going well still with yaling. Wonder how long can this last. Maybe I can't love something forever. Maybe. Who knows what's coming for us in the future? Maybe I had die. lol. Just found out that the syndrome for dengue was somehow like leukemia too. Rashes appear on skin... low platelet count. xD ha.. Luckily it wasnt leukemia for me. =) dengue is good enough.

Anyway, Bored. =}

Am I really emotionless? Unfeeling?

What is wrong with us? We were still playing game together happily. Til something in the game made her angry. I couldnt stand her attitude and talked to her harshly. Quarrelled. Being like this. This process just repeats itself on different events everyday. Smile, laugh, quarrel, cry. Becomes a routine. I couldn't stand it. I started being harsh on her attitude.

She let me know that it was my irresponsbility that made her stop being nice to me when I do things wrong. Thus her attitude. So, it was my fault. Ultimately, it strains the relationship. I hate it. I'm a carefree person. She don't like it. Too carefree she says. No plan, no goals. No emotions.

There was one time, her manager at hotel dont like her, thus stop her from working. She was sad. She called me. She started crying. I told her to stop crying. Stop crying for that bastard manager. She shouldnt cry. She got very angry with me. She says she just want someone to listen to her. She is sad. She want someone to comfort her, not to tell her to stop crying. She feels that I'm not doing my part as a BF. I told her it is ok to lose that job since it has a F-up manager. She says it is hard to find a job and a job that she likes.

I was stumped. I don't know what to do. Apologising wont help. Was I wrong? Was I really wrong? Am I that bad as a BF? I was at a loss. It happens all the time. Our characters.. Who should be the one changing? Both of us blame it on our characters. She hope I will change.

If it is that easy. Changing someone's character. 5 tears. Why won't she change then? Am I selfish? Why do I feel that she's selfish too? Aren't we all selfish?

Counting my tears. Why would I be tearing now.. when I didnt even shed one yesterday.. Countable tears.. so little.. Maybe I'm really emotionless. Oblivious..

Blog.

Seems like it happened. At least I won't make her cry for my irresponsbility anymore. I don't want to ask her back to hurt her again. Let her go.

My character...

Will I change?

Uncertain of what to do now. Prevented it from happening so many times. Hurt her that many times. My little acts that which I think was alright, hurt her so much. It's not on purpose, but it's still caused by me. Caused so naturally. Am I wrong? Where am I wrong? Why can't I feel that I'm wrong? She had told me so many times. I said sorry that many times. But I never change.

Maybe it's still the best to let her go. She's giving more than I can return.

2 drops of tears. I'm still not good enough for her.

Hmm, Bored. Bored. Bored.

www.archspace.org - playing this game now. As well as maplestory, WC3.

Sigh. I really hope some friends can play this together with me. But, all of them think it is too difficult or tough to learn to play. So I'm bored.

Nearly broke up a few times with her already. Holding on. Mixed thoughts.

Anyway, my life is still the same. But, I'm really losing hope in my life. Too bored with everything. Maybe I'm more suited for single life. It's the reverse when you are single. ROFL.

Ok. End. Nothing much to say as I'm on the phone at the moment.
