Welcome address by Guest-of-Honor
Dr. Ooi Kiang Tan, Head, Microelectronics Division, EEE, NTU
Dear invited guests and distinguished speakers, ED Singapore Chapter chair and committee members, fellow colleagues, ladies and gentlemen,
Welcome to WIMNACT-Singapore -- the third Workshop and IEEE EDS Mini-colloquium on NAnometer CMOS Technology! I would first like to congratulate the IEEE Electron Devices Singapore Chapter for organizing this one-day event, and thanks to the efforts of its committee members and the financial support from the Chapter as well as the EDS Asia-Pacific Subcommittee of Regions/Chapters and the EDS Headquarter. I would also like to thank our invited Distinguished Lecturers and speakers, both overseas and local, for their participation in the Workshop, which makes this event truly international and outstanding.
It is our honor to have the third WIMNACT being held in Singapore and associated with NTU and Microelectronics Division. The IEEE Electron Devices Society’s Distinguished Lecturer Program and its mini-colloquium series have been well known in delivering outstanding lectures, workshops, and educational programs on topics of the state-of-the-art technologies. The first WIMNACT series was initiated in November 2002, with a 9-day program in 4 cities in China: Shanghai, Nanjing, Xi’an, and Beijing. The second WIMNACT has just been held in Korea on 19 September. For this third WIMNACT, we are happy to have distinguished lecturers from Taiwan National Chiao Tung, Hong Kong UST, and Japan Hiroshima University, as well as researchers from NUS and NTU, who are eminent experts in their respective fields. The topics of the Workshop cover advanced issues in CMOS technology development in the morning session, which include low-voltage/low-power and high-speed flash memory technology, electrostatic discharge in submicron devices, and ultrashallow junction formation for sub-100nm technologies; and new device structures and modeling in the afternoon session, which include circuit models for coming MOSFET generations, nano-CMOS technology options, and the link to seamless simulation. As the mainstream CMOS technology advancements continue on the famous Moore’s Law into the nanometer regime, new issues and challenges arise in both technology development and modeling, as well as new opportunities and options in non-conventional MOS technologies. This Workshop will provide a glimpse of some important issues to be addressed in the current and future technology nodes. With the enthusiastic response as seen from more than a hundred pre-registrations before the Workshop, I am sure the audience will find this Workshop to be interesting and beneficial.
The sponsorship of IEEE and participation of international eminent experts in WIMNACT is also very timely as Singapore and Asia-Pacific region is embarking on joining the global semiconductor roadmap of advanced technologies. This is witnessed by more than 80 pre-registrations received from local industries and neighboring countries. We are also very glad to have this opportunity to demonstrate our existing and new programs in the area of nano-CMOS in the Microelectronics Division, which will be briefed by our Program Directors for the Silicon Technology and Computational Nano-Electronics research groups. We have also planned a session for interested staff to interact with the invited speakers, and a lab tour for our invited guests at the end of the Workshop.
On behalf of the Microelectronics Division and the School of EEE, it is my great pleasure to extend a warm welcome to everyone attending this Workshop, and I wish all of you a pleasant day in NTU for a successful Workshop. Thank you!
Abstract:
The floating gate flash memory has been one of the most successful nonvolatile memory in the past two decade. However, it requires high gate voltage for programming and erase which limit the device scaling and reliability. In this talk, we will address different strategies for designing floating gate flash memories with high performance and high reliability, for achieving low power and high speed performance. Various schemes and cell structures will be introduced to meet the low voltage, low power, and high speed requirements. Also, the possibility for a further scaling of flash memory cells based on different gate oxide engineering will be presented.

Abstract:
In the fabrication of ultra-large scale integrated circuits, one crucial step is to shrink the critical dimension of the polycrystalline silicon gate. As a result, short channel effects (SCE) become more prominent and thus ultra-shallow junctions are needed to prevent SCE. After ion implantation to dope the source/drain extensions, the wafers are normally subjected to a high-temperature anneal to activate the dopants. Due to the transient enhanced diffusion (TED) of boron, there is a lot of concerns on the thermal budget of the post-implantation anneal. Ultra-shallow junctions can be obtained by using ultra-low energy ion implantation followed by spike rapid thermal annealing (RTA). An extreme case of RTA is laser thermal processing (LTP), which involves the laser irradiation of the silicon substrate with ramp-up rates so high that it can melt the surface regions, without melting the bulk.
The results of ultra-shallow p+/n junctions fabricated using pre-amorphization of silicon to enhance melting of silicon during LTP will be presented. Comparison will be made to spike annealed junctions. Recent results of using non-melt approach will be shown. The effects of the substrate type such as bulk silicon and silicon on insulator on LTP will be discussed.

Abstract:
Requirements for circuit simulation are increasing due to two ongoing developements, namely, the down scaling of MOSFETs into the sub-100nm regime and system integration with many different functions on a single chip. To assist in the development, the most important modeling issue is to guarantee sufficient simulation accuracy and applicability for any advanced technology. Here we discuss different modeling approaches, with emphasis on surface-potential-based models, to realize the requirements.

Abstract:
In this presentation, the requirements for nano-CMOS devices will be reviewed. Various technology options including high-k dielectrics, metal gates electrode, source/drain engineering, strained silicon, and Schottky source/drain will be examined. While these technology options provide potential solutions to the scaling crisis of traditional CMOS technology, their utilization remains challenging and results in new issues. The migration to non-traditional device structure such as double-gate MOSFETs, multi-gate quantum wire FET and single electron transistor has been actively pursued. New challenges and opportunities in the application of these new devices will be discussed.

Abstract:
The trends and needs in multi-level modeling of ULSI systems are reviewed in the context of nanometer CMOS technology, with an emphasis from the model/tool developer’s perspective. A dual representation of transistors/circuits is proposed and demonstrated through physics-based transistor compact modeling and a single-engine circuit simulator. Extension to process correlation and block-level representation is also proposed, which will be the key to studying process effects on system performance. This consistent dual representation allows detailed physics captured at a lower level to be propagated to the higher level of abstraction. The key idea is to build a physics-based device compact model (CM) based on technology characterization, which serves as the building block for an implicit multi-level circuit simulator based on a subcircuit-expansion approach. In this way, process variation can be captured through device CMs, and its effects on circuit/system performance can be linked to a consistent hierarchy of abstractions within the same simulator engine.
