The waiting is finally over...
I have in the past lamented how slow my research was and was having a second thought about taking up an academic position. With this award, I am all ready to undertake this new endeavor.
Early this year I was turned down for the NRF Research Fellowship when I faced with a group of high caliber and accomplished young researchers who have a long string of credentials to their credit (we are talking about paper in Science/Nature, Patents, Nobel Laureate's advisee, etc). Naturally I was upset and uncertain. With this new support, I am in a more comfortable position to take my research to another height, and hopefully this is a first step towards more grants.
By the way my laptop is in bad condition, I will need to ask for a new one from the school.

Best of Luck to Shian Ling
I paid respect in a nearby Temple before heading home. I got off a few stops ahead thinking that I should walk instead of letting bus 199 making a big loop around the campus. Not a wise decision I must tell. It started pouring as soon as I got off and I took shelter at the information booth. It got worse and there was no way I can escape so I waited. Twenty minutes passed and this kind gentleman pulled his car over and asked if he can give me ride. YES was my answer! I did not ask for his name, but he told me he was a former NTU student and he was back to study for external exam. Thanks dude, you were a great help or less I might have to wait for 1 more hour and risking myself of getting cold. The message? Never stop hoping!
I have just returned from Japan one week early and you want to know my biggest impression? The moment I sat on their toilet bowl, I knew this is a truly technological country. If you have been there, you know what I mean!
My laptop has been stalling on me, waiting to get it back from the IT people.

Method of forming a multi-layer semiconductor structure incorporating a processing handle member
A method of forming a multi-layer semiconductor structure includes attaching a handle-member to a top surface of a first structure using a first interface. At least one region of a bottom surface of the first structure is etched to form at least a first via-hole for exposing a portion of a first conductive member defined on the first structure. A conductive material is disposed in the first via-hole such that a first end of the conductive material is in electrical communication with the first conductive member and a second end of the conductive material is exposed at the bottom surface of the first structure. A second interface is disposed over at least the second end of the conductive material, which serves as a bonding and/or electrical interface between the first conductive member defined on the first structure and a second structure of the multi-layer semiconductor device structure.

Edited Book... stay tuned (June 2008)
http://www.springer.com/east/home/engineering/electronics?SGWID=5-191-22-173781598-detailsPage=ppmmediaaboutThisBookWafer Level 3-D ICs Process Technology
Series: Series on Integrated Circuits and Systems
Tan, Chuan Seng; Gutmann, Ronald J.; Reif, L. Rafael (Eds.)
2008, Approx. 420 p. 105 illus., Hardcover
ISBN: 978-0-387-76532-7
Due: June 2008
Overview of Wafer Level 3-D ICs.- Monolithic 3-D Integrated Circuits.- Stacked CMOS Technologies.- Wafer Bonding Technologies and Strategies for 3-D ICs.- Through Silicon Via Fabrication, Backgrind, and Handle Wafer Technologies.- Cu Wafer Bonding for 3-D ICs Applications.- Cu/Sn Solid-Liquid Interdiffusion Bonding.- An SOI-Based 3-D Circuit Integration Technology.- 3-D Fabrication Options for High Performance CMOS Technology.- 3-D Integration Based upon Dielectric Adhesive Bonding.- Direct Hybrid Bonding.- 3-D Memory.- Circuit Architectures for 3-D Integration.- Thermal Challenges of 3-D ICs.- Status and Outlook.
Wafer Level 3-D ICs Process Technology focuses on foundry-based process technology that enables the fabrication of 3-D ICs. The core of the book discusses alternative technology platforms for pre-packaging wafer level 3-D ICs, with an emphasis on wafer-to-wafer stacking. Driven by the need for improved performance, a number of companies, consortia and universities are researching methods to use short, monolithically-fabricated, vertical interconnections to replace the long interconnects found in 2-D ICs. Stacking disparate technologies to provide various combinations of densely-packed functions, such as logic, memory, MEMS, displays, RF, mixed-signal, sensors, and power delivery is potentially possible with 3-D heterogeneous integration, making this technology the "Holy Grail" of system integration.
Written for:
Professionals and engineers in the field of 3-D ICs
Applications enabled by 3-D integration
Three-dimensional (3-D) integration
Through Silicon vias (TSVs)
Wafer bonding

Glad we made it to 2008 (and counting)
I think like most people, I have a set of general resolutions: health comes in first, followed by harmony relationship with family/friends/colleagues, do well in research (a few journal articles, a few conference trip, new grants, etc, would not hurt), and of course material gain! More specific resolutions include:
(1) it is time to think about getting a car and driving again!
(2) learning how to swim... no more swimming at the edges;
(3) keep fit - it comes with dieting and work out;
(4) a relationship? (According to Chinese Horoscope, 2008 is a great year for romance for rabbits).
These are certainly not wishful thinking and are certainly achievable with the right effort. I am excited about 2008, I can feel a lot of positive changes are taking place this year.
I am only one more chapter short to the edited book on 3-D for Springer - very close now. Hope UCSB folks will cooperate and send it asap... It has been too long and I want to move on with my life!

IEDM 2007, Washington, DC
JMeindl -> KSaraswat -> RReif -> CSTan
So I am certainly very honored to be part of this chain.
A few highlights:
- flight SQ26 was delayed for 1.5 hrs due to technical issues with the aircraft and a replacement was made. But we made it in JFK just on time nevertheless;
- at JFK I went through the special registration procedures again and was the last one to collect my baggage;
IEDM highlights:
- I took a shortcourse on Nanotech/Nanoelectronis - I liked the one given by del Alamo on 3-5 CS for logic applications, and enjoyed Lieber's talk on NWs (the assembly approaches he talked about were intriguing);
- I didn't really enjoy the rest of the 3 talks;
- The CMOS performance boosters course seemed interesting;
- There is true 3D paper to the best of my knowledge (and a few are related in some ways). Takafumi invited me to visit his lab in Tohoku if I made it to 3-D SIC (will see);
- There was a session on energy harvesting and a great talk on Si PV was given;
- met many big names and old faces (there is a strong MIT presence here, I think MTL must be empty during this week). MTL-ers include: DAA, JHoyt, JdelAlamo, Tayo, Duane (didn't talk to him), Gene, Vicky, Chang-Lee (LL), Ali, John, Liang, Niamh, DH Kim, Charles C, Tony, JFiorenza, etc;
- had a one-on-one with Tayo and he bought me wine (first time);
- The GOLD seminar was great so was the dinner. Was great to meet Janice and John Kymissys;
- NUS and IME did very well. How about NTU?
- at the panel session, DAA at the closing remark, based on show of hand (question: would FETs remain in gadgets in 2030?), concluded jokingly "FETs has a bright future, and there is plenty of room at the top to integrate on Si". I liked this line. I first used this line at my PhD thesis defense on Nov 14, 2005 based on a talk Feynman gave in 1984. Great, now it is official!
What happened in DC remain DC. I look forward to IEDM 2008 in Bay Area and hope to contribute in IEDM 2009 in DC. Hope this is an ahievable goal.
So long.

Deal or No Deal
Last night the someone walked away with S$45,000 with a much much smaller amount in the case she picked. Tonight, for the first time, someone picked a S$250,000 case... only to walk away with S$40,000. I can understand why she burst out at the end...
Is playing DONO a pure luck determined game? How to win big? How do you know when to stop and to proceed? I don't have good answers that I find convincing.
I want to play too!!!!!!!!!!
Leaving for DC and Atlanta in a week!

Memories
Part of my intention of having this blog, besides to "report" my interesting (or boring) daily encounters, is also to bring back some of the past memories. I was skimming through my external hard-disk and was digging out some old files. I found this picture of three cutes boys (IJ's going to love this) by the port of P-Town. OK, if you do not know, P-Town is Province Town right at the tip of Cape Cod in Massachusetts. This is probably one of the most lively (and rather unique too) places in the US! I must have been there for some 3 times? It is an interesting place because it is a gay (and lesbian too) town! IJ used to have this dream to move to P-Town but gave up when I told him that this town is probably a dead town in the winter.
Anyhow, JH drove me and IJ in this trip. It is a nice 1 and 1/2 hr drive from Boston. I was the navigator as usual and I can't recall we made any serious mistakes. It was upon IJ request during one of his post-Harvard visit to Boston. It was a sunny morning/afternoon though it turned really chilly at night. I recalled we had brunch at this restaurant and we ordered a piece of cake to share. We cleaned the plate and the waiter jokingly told us "get another piece, don't eat the plate." On our way back we patronised this Thai restaurant, which wasn't not at all good by JH and my standards let alone IJ's. As charming as he was IJ starting talking to this waitress and found out her stories. Apparently she left her little daughther in Thailand to work here for a living and she was sick from some illness.... OK, it wasn't fun to hear this.
My memory of this trip is vague now, but this picture can possibly tell you we had a great time in P-town. (I can't recall who took us this picture though, someone random?)
CLieber of Harvard is in town at NTU this week and it created quite a sensation among us. The part I like most about him is that he is quite down to earth and unpretentious... but I think he should probably be more gentle come to hand shaking (it can hurt your wrist!).

Go Mich, Go!
Go Michelle, Go!
Blogs... just how many?
- blog search engine Technorati tracks nearly 100 million blogs;
- nearly 200, 000 new ones added every day;
- according to market research firm Gartner (Stamford, CT), there are more than 200 millions abandoned blogs.
Some numbers for you to digest. Does anyone have similar numbers for social networking sites? I could remember e-group, yahoo group, hi5, friendster, MySpace, facebook and most recently OpenSocial (google's initiative)? How many are active and how many are abandoned?

food poisoning or was it me?
I was at the ICA building Tuesday waiting to collect legal documents when I bumped into Jon and decided to have lunch together. I ordered fried noddles. It started to feel funny even before I finished my plate and it disturbed me the whole afternoon. It does not take an expert to tell that the noodle was stale... (but edible). That night, I vomitted and sat on toilet bowl a few times. Bad. The next day I felt so lousy that I cancelled dinner appointment with IJ and stayed at home doing absolutely nothing. Even now it is still feeling funny but my appetide has improved though not completely. Could it be because I picked it from hometown last weekend?
I noticed that I get sick easily from food. Like the Chinese proverb goes "you get illness from what you eat, you get into troubles from what you say," - I can testify to that. Do you have similar problem?
I was at Suntec earlier attending a SUSS roadshow. I cut it short after lunch - partly sick, partly because the topics didn't really interest me a whole lot.
This is TGIF and I have low appetide. Need some love here.

Sleepless in Cupertino, CA

I was greeted by immigration officers at SFO who were polite and felt bad that I needed to go through the special registration thingy - all Malaysian males must go through this regardless of ethnicity. Just follow the law I guess. I almost lost Arafat's racket while waiting for Zulina...
Zulina picked me from the airport and we headed south. Noubar is on overseas trip. She had nasi lemal ready for me! We spent Sunday around the area. I checked in the hotel early Monday morning and met Ron to discuss matters related to the book in the evening. It was a little cold for me... I miss Singapore heat! I had such a terrible dinner Monday night that Zulina decided to take to Chinese buffet Tuesday night.
My presentation was yesterday. It went OK, not great. I decided to cut it short and moved back with Zulina to prepare slides for Sematech workshop. Changed my flight to Boston a day earlier.
The following days I will meet Jason, CK, George, and possibly Sharon before heading to Boston. Am anticipating... hope those in Boston will save me some nice weather... I have low tolerence for nasty weather now.
My jet lag is not completely gone yet... I woke up at 4:30 this morning CA time :(
BTW, did I tell you I met Sirirat the Thursday before? We had such a sumptuous steamboat dinner... but didn't make it to the Ang Moh Dessert on Beach Road (Belgian waffle in hawker center). She remained lovely!

What happens in Vegas, stays in Vegas
It was a lovely evening. I will meet DC again in Boston in Oct! She will spend a semester in Boston, on leave from IC. Maybe this time I will buy her a drink? As Cage quoted in the movie, "What happens in Vegas stays in Vegas." I will put it as "What happens in Tanglin Club stays in Tanglin Club". :P
I should start preparing for my US trip today.
