Home-Grown Transparent Thin Film Transistor Developed
KAIST, Aug. 6, 2008 -- A KAIST research team led by Profs. Jae-Woo Park and Seung-Hyup Yoo of the Electrical Engineering Division has developed a home-grown technology to create transparent thin film transistor using titanium dioxide., university authorities said.The KAIST team made the technological advance in collaboration with the LCD Division of Samsung Electronics and the Techno Semichem Co., a local LCD equipment maker. Transparent thin film transistor continues to enjoy a wealth of popularity and intensive research interest since it is used in producing operating circuits including transparent display, active-matrix OLED (AMOLED) display and flexible display.
The new technology is significant in that it is based on a titanium dioxide, the first such attempt in the world, while the technologies patented by the United States and Japan are based on ZnO.
Researchers will continue to work on securing technological reliability and developing a technology to mass-produce in a large-scale chemical vapor deposition equipment for the next couple of years.
"The development of technology to produce transparent thin film transistor will help Korean LCD makers reduce its dependence on foreign technologies, as well as maintain Korea"s status as a leader of the world"s display industry," said Prof. Park.
KAIST has applied for local patent registration of the technology and the process is expected to complete by this October or November. International patents have been also applied for in the U.S., Japan and Europe.
The new technology was introduced in the latest edition of the Electron Device Letters, a journal published by the Institute of Electrical and Electronics Engineers or IEEE, a New York-based international non-profit, professional organization for the advancement of technology related to electricity. It will be presented at the International Display Workshop 2008 on Dec. 5 in Niigata, Japan.

KAIST Professors Article Featured as Cover Thesis of Biotechnology Journal
An article authored by a research team of Prof. Sang-yup Lee at the Department of Chemical and Biomolecular Engineering and Dr. Jin-Hwan Park at the KAIST Institute for the BioCentury has been featured as the cover thesis of the August 2008 issue of Trends in Biotechnology.
The paper, titled "General strategy for strain improvement by means of systems metabolic engineering," focuses on the application of systems biology for the development of strains and illustrates future prospects. Trends in Biotechnology, published by Cell Press, is one of the most prestigious review journals in the field.
Jin-Hwan Park, the primary author of the research thesis, said that the KAIST team"s research work was expected to provide substantial help to researchers involved in biotechnology industry.
The strategy has been established on the basis of the experiences gained in the actual microbial production process using the systems biology methods which his research team has recently worked on, Prof. Park said.

KAIST to build large-scale civil engineering experiment center
- Geo-Centrifuge experiment center of an area of about 1,712 square meters and an estimated construction cost of total 8.4 billion won
- Simulation laboratory in the field of geotechnical engineering with state-of-the-art experiment equipment- Ground-breaking ceremony held on April 3 at 4 pm
KAIST will construct ‘distributed shared-type Geo-Centrifuge experiment center’, a large-scale civil engineering laboratory that will study natural disasters such as earthquake, embankment collapse, etc. with ground structure miniatures.
A two-story building with a basement occupying an area of about 1,712 square meters will become a landmark laboratory in the field of geotechnical engineering that can be used for the education, research, and social infrastructure design by universities, institutes, and corporations via high-speed information and communication network. The estimated construction cost is 8.4 billion won.
The center will be composed of experiment building including geo-centrifuge laboratory, model-making room, workshop, geotechnical engineering laboratory, and specimen storehouse; and research building including control room, video conference room, electronic library, and research rooms. A variety of convenience facilities for researchers and video conference and remote monitoring system, with which researcher at remote distances can directly participate in experiments, will be provided in the research building, and world’s top-class experiment equipment such as geo-centrifuge with a turning radius of 5 meters, a maximum acceleration of 130 G (130 times faster than the acceleration of gravity), a preload of 2,400 kg and bidirectional shaking-table that can reproduce earthquakes-like wave during experiments, and robots that can reproduce construction procedures by a remote control will be installed.
Geo-Centrifuge experiment refers to an experiment that reproduces natural disaster-like motions by making miniatures of large-scale ground structures such as dams, slopes, etc. and using centrifugal forces generated from high-speed rotation. This experiment can easily and rapidly reproduce actual motions of ground structures at a low cost, thereby being widely used for various geotechnical engineering researches such as evaluation of seismic safety, movement of soft ground, slope stability analysis, etc. The causes of the embankment collapse in New Orleans by Hurricane Katrina in 2005 were also revealed by simulation tests by this experiment.
“The center will make possible a variety of experiments and researches that have never been available in Korea due to the lack of experiment infrastructure, therefore activate researches over the design and construction of large-scale social infrastructures. Making possible civil engineering researches demanding the use of large-scale equipment like Centrifuge, severely dependent on overseas technologies so far, will enhance the global competitiveness of Korean construction industry,” said Dong-soo Kim, President of the center.
The center will be constructed as part of the Ministry of Construction & Transportation (MOCT)’s project for the establishment of distributed shared-style construction research infrastructure, which is designed to establish construction research infrastructures in a national level. The ground breaking ceremony was held at KAIST on April 3 at 4 pm.

KAIST-Tsinghua High-Tech EXPO 2004
THE KAIST Herald 2004.5.12
By Jong-kyoung KimThe KAIST Herald Staff Reporter
KAIST and Tsinghua University are holding KAIST-Tsinghua Korea-China High Tech EXPO 2004 from July 12 to 14, at the Beijing International Convention Center. The Expo seeks to contribute to economic development through promoting exchanges between exceptional Korean and Chinese start-up companies, and to promote cooperation between high-tech industries and academic institutions through academic and technological exchanges between each nation"s best technology institutions.
The Expo is a big international affair held by a university from Korea and one from China. The Expo is also a means to implement the agreement between KAIST and Tsinghua in 2002 to promote exchanges between the two universities and to conduct international co-research. It is sponsored by various technology institutions of both nations.
The Expo is different from other expos in that it is a specialized expo where Tsinghua-related companies, experts, and buyers participate to discuss the transfer of technologies and to deal in trades. Also, to insure that the Expo is beneficial to participating Korean companies, the Expo plans to offer business talks with at least ten Chinese companies per company. From Korea, thirteen companies from enterprise-incubation center and graduate start-ups with high-tech start-ups in areas of IT, BT, NT and mechatronics that are possible in exporting related products or transferring related technologies are participating. From China, Tsinghua-related companies, China Telecom, China Unicom, and other companies under China Telecommunication Association with other famous Chinese companies are expected to participate.
In addition to exhibitions, co-work between KAIST and Tsinghua"s research centers and KAIST"s Technology Transfer & Exchange Center"s explanation on public technology transfer are taking place during the Expo.
And, after three days of the Expo, about ten companies will move to Chungking, a city in western China to hold a product and technology explanation session.
