In Loving Memory: Madam Ooi Lian Chu (1935-2008)

It is with immense sadness I announce that my Mom passed away on June 8 (Sunday) at the age of 72. She succumbed to complications from pneumonia. It was all too sudden and it does not make any sense at all. I am sad and coping. I know she and Dad are now in a much better place, but I can't possibly tell you how much they will be dearly missed and constantly remembered. They are examples of humble parents who made ends meet for the children with unconditional love. I consider myself very lucky. Truly, the love of parents is boundless and there is no way one can repay. My regret, she didn't live to see the new house ready (in 1-2 more months).

I urge you to be kind to your living parents. On this note, I pay homage to all Mothers.

The waiting is finally over...

On Wednesday 4:15PM, the Chair of the School sent me an email that will change the whole course of my stay in Singapore. It is a sharp turning point, if you will. This was a two-line email, but it was definitely the one that would make me excited for many days. After almost 8 months of screening and debate, the university management has agreed to grant me the inaugural Nanyang Assistant Professorship. It is not about the title, but it is about the amount of start-up grant that comes with it. In principal the university can fund up to S$1M for my work, subject to approval of the final budget. Too bad I do not have more details on this as the time of writing, but it can only be better than now!

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 met Shian Ling yesterday at Jurong Point. In less than 3 months, she will be returning to Duke in Durham, NC, to pursue doctoral study. So in a way this is farewell lunch, though she did not seem to like the idea of being away for the next 5 years (actually she perfers to look at it as being away for 1 year as she plans to visit home everyday year). She asked why hadn't I been updating my blog. Well, these past months have really been dull and I really do not anything interesting to write. All funding proposals were turned down and I am not any different one year ago:(

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

Abstract

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.

About this book
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.
Wafer Level 3-D ICs Process Technology is an edited book based on chapters contributed by various experts in the fields of wafer-level 3-D ICs process technology and applications enabled by 3-D integration.

Written for:
Professionals and engineers in the field of 3-D ICs
Keywords:
Applications enabled by 3-D integration
Three-dimensional (3-D) integration
Through Silicon vias (TSVs)

Glad we made it to 2008 (and counting)

2007 was a pretty good year for me. Job was pretty good (not to mention my saving has gone up several folds and I can now afford many items on my wish list). Minor complaints? Of course, but I liked 2007 overall. The natural question to ask is so what are your new year resolutions?

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!
