National Project on 45 to 32 nm Metal Oxide Semiconductor Field Effect Transistors for Next Century IC Fabrications

It is well known that the Taiwan Semiconductor industries play the very key roles for the worldwide IC foundry, and the advanced research of nanoelectronics is the lifeline for its long term developments. Professor Huey-liang Hwang effectively integrated the most outstanding research team and resource in Taiwan on the National Project on Nanometer CMOS Transistors for the 21 century, which is sponsored by the Ministry of Economic Affairs of ROC. A dozen of Professors from NTHU (National Tsing Hua University) with expertise at the novel materials and analysis and NCTU (National Chiao Tung University) with expertise at devices and reliability are devoted to the studies and are in collaboration with the world-wide-known company such as TSMC, and breakthrough of the key technologies of 45-32 nm technologies are achieved. The objective of this project is focused on the development of advanced metal gate/high-k MOSFET for 45 nm node generation and beyond, the efforts include the thermal stability of HfO2, HfAlOx alloy and Al2O3/HfO2 stack, prepared by ALD were compared, the incorporation of Al in alloy form gave superior characteristics by retaining an amorphous structure up to 1000°C, which suppress the leakage current and retards growth of the interfacial layer giving the least increment of EOT and interface traps. Besides, by incorporating Al into TiO2 gave an EOT value of the Al2O3/TiAlOx/Al2O3 film down to 0.8 nm. Furthermore, high selectivity was obtained via etching the HfAlO and silicon wafer with pattern using the ICP Plasma. In this project, YbSi metal gate for n-MOSFET and IrSi metal gate p-MOSFET were successfully fabricated for the HfAlON MESFET. The results showed the good effective workfunction of 4.15 and 4.9 eV and no degradation of gate dielectric current and mobility in the YbxSi/HfAlON and IrxSi/HfAlON FUSI-gates by reducing the metal diffusion at lower temperatures.

Enhancing the Role of Universities in Building National Innovative Capacity in Asia: The Case of Taiwan

Taiwan has already demonstrated how a Newly Industrializing Economy can build an export-oriented manufacturing system driven by catch-up strategies linked to knowledge leverage via public institutions. In the 1990s, Taiwan moved toward building its innovative capacity, and in the 2000s it is drastically upgrading the role of universities in providing fundamental R&D, in acting as incubators of new, knowledge-based firms, and in building the country’s innovative potential through IP protection and commercializing activities. This study examines how these new approaches are being implemented in three universities, in National Chiao Tung University (NCTU), National Tsing Hua University (NTHU)—both located in the Hsinchu high-tech belt—and National Taiwan University (NTU) located in the Taipei metropolitan area, as well as in the Industrial Technology Research Institute (ITRI). ITRI has been the engine that drives Taiwan’s technological upgrading, and continues its role through new emphases on patenting and entrepreneurial technology transfer.

Urinary 1‐Hydroxypyrene Level Relative to Vehicle Exhaust Exposure Mediated by Metabolic Enzyme Polymorphisms

Polycyclic aromatic hydrocarbons (PAH) are common air pollutants generated from incomplete combustion. The inhalation of exhaust fumes in urban areas has been suggested to be an additional contributing factor. This study investigated the influence of urban traffic exposure, personal lifestyle factors and metabolic enzyme polymorphisms on the urinary 1-hydroxypyrene (1-OHP) level, approximating exposure to PAH. With consents, 95 male taxi drivers exposed to vehicle exhaust in traffic and 75 male office employees received health interviews and provided urine samples. The results showed taxi drivers had higher urinary 1-OHP than the office employees (mean +/- standard deviation were 0.17 +/- 0.10 vs. 0.10 +/- 0.07 mol/mol creatinine, p<0.001). The average urinary 1-OHP level increased from 0.07 micromol/mol creatinine for non-smoking office employees to 0.17 micromol/mol creatinine for those who smoked more than 20 cigarettes daily. The values for taxi drivers with similar smoking statuses were 0.12 and 0.25 micromol/mol creatinine, respectively. Among non-smokers, taxi drivers still had higher 1-OHP level than office employees (0.12 +/- 0.05 vs. 0.07 +/- 0.03 micromol/mol creatinine). The subjects with the m1/m2 or m2/m2 genotype of CYP1A1 MspI or GSTM1 deficiency had significantly higher urinary 1-OHP levels than those with other CYP1A1 MspI and GSTM1 genotypes. Multivariate logistic regression analysis showed that taxi drivers (adjusted odds ratio (OR)=5.1, 95% confidence interval (CI)=1.1-13.6), smokers (OR=5.5, 95% CI=1.6-18.4) and subjects with the m1/m2 or m2/m2 genotype of CYP1A1 MspI (OR=9.7, 95% CI=2.7-35.0) had elevated urinary 1-OHP (greater than the overall median value, 0.11 micromol/mol creatinine). The results of this study suggest smoking contributes to the elevated urinary 1-OHP levels in taxi drivers in addition to taxi driving, and the excess level contributed from traffic exhaust and smoke was regulated by the CYP1A1 MspI genotype. Traffic exhaust exposure, smoking and CYP1A1 MspI genotype contributed to the variation in levels of urinary 1-OHP excretion.

Darwin Chang

Darwin Chang, a prominent theoretical physicist, succumbed to stomach cancer on 29 December 2005 in Taipei, Taiwan.Darwin was born on 29 June 1954 in Taichung, Taiwan. After undergraduate study in physics at National Taiwan University, he received his PhD in particle theory from Carnegie Mellon University in 1983 under one of us (Wolfenstein). His creativity, productivity, and passion for physics were already apparent at Carnegie Mellon. He worked so quickly and independently after discussing an idea with Wolfenstein that the two somehow never published together. A paper he authored by himself on spontaneous CP violation is well cited.In 1983 Darwin moved to the University of Maryland in College Park as a postdoc, and he flourished there. In just three years, he published with Rabindra Mohapatra and others more than 30 papers on left–right models, SO(10) grand unification, neutrino physics, and numerous other topics. In the words of Mohapatra, “It was so much fun and so stimulating to discuss physics with Darwin. He was not only an extremely insightful physicist, but he was among the hardest-working and [most] brilliant collaborators that I have known in my lifetime.”Darwin joined the faculty of Northwestern University in 1986, and in 1987 he received the Outstanding Junior Investigator award from the US Department of Energy. He soon started a lifelong collaboration with one of us (Keung) in which we produced nearly 50 publications.In 1993 Darwin became a professor of physics at National Tsing-Hua University in Hsinchu, Taiwan. He continued to expand his research interests, which eventually encompassed hyperon weak decay, top-quark spin and CP violation, sand piles, black holes, and even d-wave superconductivity. In one notable work with Keung and Apostolos Pilaftsis, he found new two-loop contributions to electric dipole moments, a result that provided one of the most stringent constraints on supersymmetric models. Darwin was a strong force behind the promotion of fundamental science research in Taiwan. He served as president of the Physical Society of the Republic of China and was instrumental in the establishment of the National Center for Theoretical Sciences in 1997. He set up successful exchange programs between NCTS and other high-energy physics labs, including KEK in Japan, and served as the director of the NCTS physics division in 2004.Open, honest, and down to earth, Darwin could also be critical in discussions. He always managed a cheerful smile and had a hallmark laugh. His energy and passion for physics was reflected in his skiing style: Regardless of obstacles, charge! Everything under the sun was physics for him; the only question he asked was, Is it interesting? Curiosity was a key word in his life, and adventure took the highest priority. He loved teaching and took great care of his students. Even during his final months, he tried hard to spend time with them. His presence and insightful comments were always stimulating at seminars. A week before his death, one of us heard him say as he lay in the hospital, “Oh, if I could just go to a seminar. …”Darwin’s interests extended to music, sports (swimming and skiing), and poetry. It is fitting to close with a few of his verses: All my life,I’ve been trying to find,after every beautiful soul I encountered,after every unfulfilling dream I blundered,a joyful peace in my human weakness,to accompany me to my willing decease. His decease may not have been willing, but he has now attained eternal peace.Darwin ChangPPT|High resolution© 2006 American Institute of Physics.

An Undergraduate Nanotechnology Course for Classes of Multi-discipline students in Taiwan

ABSTRACTWe reported on our experiences with teaching several semesters of undergraduate nanotechnology courses at both the National Tsing Hua University (NTHU) and National Dong Hwa University (NDHU) in Taiwan. Students who were enrolled in our classes at NTHU represented many different disciplines, but mainly in the physical sciences, engineering and life sciences. In contrast, students who were enrolled in our classes at NDHU dominated in the social sciences and arts. There were some interesting differences in addition to the similarities in their attitude toward the nanotechnology. Since this course is aimed at introducing the nanotechnology to students trained in different disciplines, we emphasized the fundamentals, current status, potential applications, and possible consequences of nanotechnology. This course also explored the close ties between nano-science and engineering (NS/E) and our daily life. Furthermore, this course elaborated on the interrelationships of NS/E with other subjects, particularly the biomimetics, smart systems, and biotechnology.

The FEL and IFEL design study for the proposed NTHU photon–electron dynamics laboratory

A photon–electron dynamics laboratory is being proposed at National Tsinghua University, Taiwan. The mission of the proposed laboratory is to conduct advanced research on free-electron laser, inverse free-electron laser, and laser-driven particle acceleration. We discuss in this paper the design study of the Stanford high efficiency FEL and the reconfigured Stanford/TRW wiggler in the proposed laboratory. The Stanford high efficiency FEL is to demonstrate a 19% beam-to-laser efficiency. The reconfigured, 1-m Stanford/TRW wiggler may serve as an inverse FEL that provides 1.5-μm bunched electrons for various kinds of laser-driven acceleration experiments.

Cold fusion experiment at Department of Nuclear Engineering, National Tsing-Hua University

We have repeated the so-called cold fusion experiment by electrolyzing heavy water, with 0.1M LiOD, with palladium rod as the cathode and platinum wire as the anode. The purpose of our experiment is to dectect the neutrons that are produced from the fusion process of deuterium if fusion does occur. We use one3He detector and one BF3 detector to detect the thermal neutrons coming out of the water bath that surrounds the heavy water cell. Possible neutron bursts are detected by the3He detector during a period of about 7 h after electrolyzing for 11 days.

Conference on Experimental Biology, Peiping

MORE than one hundred teachers, research workers and senior students in biology of the universities and institutions of Peiping met in the new campus of the College of Agriculture of the National Tsinghua University during July 17– 25. The instigator of the conference was Dean P. S. Tang, ably and generously assisted by his colleagues of the College. The campus is next to the famous Summer Palace which was freely accessible to the members during this conference, and one of the most enjoyable parts was the boating at night on the lake inside the Palace. Preliminary meetings consisted of lectures on the place of biology in ancient Chinese history, and on the teaching methods of biology in colleges and high schools. So many contributed valuable suggestions to the latter subject that a special committee was appointed to explore further this important and fertile field. The regular programme consisted of symposia and lectures on recent advances in genetics, hormones, nutrition, viruses and rickettsia, biophysics and aviation physiology. The round-table meetings were attended chiefly by senior members, and the following topics were discussed : cytology, growth and development, immunity, and effect of temperature on organisms. The general impression of the conference was that the time allotted to each speaker was too short, and plans are being made to choose one or two important subjects as the theme of the conference next summer. It was fortunate that the Peiping branch of the Chinese Society of Phytopathology was able to meet with the conference on the afternoons of July 20 and 21.
