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

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

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.

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

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

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.

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.

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.

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.
