A Team of Three PhD Candidates Wins the Korea Semiconductor Design Contest
“We felt a sense of responsibility to help the nation advance its semiconductor design technology” A CMOS (complementary metal-oxide semiconductor)-based “ultra-low noise signal chip” for 6G communications designed by three PhD candidates at the KAIST School of Electrical Engineering won the Presidential Award at the 22nd Korea Semiconductor Design Contest. The winners are PhD candidates Sun-Eui Park, Yoon-Seo Cho, and Ju-Eun Bang from the Integrated Circuits and System Lab run by Professor Jaehyouk Choi. The contest, which is hosted by the Ministry of Trade, Industry and Energy and the Korea Semiconductors Industry Association, is one of the top national semiconductor design contests for college students. Park said the team felt a sense of responsibility to help advance semiconductor design technology in Korea when deciding to participate the contest. The team expressed deep gratitude to Professor Choi for guiding their research on 6G communications. “Our colleagues from other labs and seniors who already graduated helped us a great deal, so we owe them a lot,” explained Park. Cho added that their hard work finally got recognized and that acknowledgement pushes her to move forward with her research. Meanwhile, Bang said she is delighted to see that many people seem to be interested in her research topic. Research for 6G is attempting to reach 1 tera bps (Tbps), 50 times faster than 5G communications with transmission speeds of up to 20 gigabytes. In general, the wider the communication frequency band, the higher the data transmission speed. Thus, the use of frequency bands above 100 gigahertz is essential for delivering high data transmission speeds for 6G communications. However, it remains a big challenge to make a precise benchmark signal that can be used as a carrier wave in a high frequency band. Despite the advantages of CMOS’s ultra-small and low-power design, it still has limitations at high frequency bands and its operating frequency. Thus, it was difficult to achieve a frequency band above 100 gigahertz. To overcome these challenges, the three students introduced ultra-low noise signal generation technology that can support high-order modulation technologies. This technology is expected to contribute to increasing the price competitiveness and density of 6G communication chips that will be used in the future. 5G just got started in 2020 and still has long way to go for full commercialization. Nevertheless, many researchers have started preparing for 6G technology, targeting 2030 since a new cellular communication appears in every other decade. Professor Choi said, “Generating ultra-high frequency signals in bands above 100 GHz with highly accurate timing is one of the key technologies for implementing 6G communication hardware. Our research is significant for the development of the world’s first semiconductor chip that will use the CMOS process to achieve noise performance of less than 80fs in a frequency band above 100 GHz.” The team members plan to work as circuit designers in Korean semiconductor companies after graduation. “We will continue to research the development of signal generators on the topic of award-winning 6G. We would like to continue our research on high-speed circuit designs such as ultra-fast analog-to-digital converters,” Park added.
Transparent Antenna for Automobile Developed
A research team led by Prof. Jae-Woo Park of the School of Electrical Engineering & Computer Science, KAIST, developed a transparent antenna for the next-generation automobiles, university authorities said on Monday (Aug. 17). The development was made possible through joint researches with the Hyundai-Kia Automotive Group; Winncom, a car antenna manufacturer; and a group of researchers led by Han-Ki Kim of the Department of Display Materials Engineering at Kyung Hee University in Seoul. The transparent antennas were developed in two kinds -- one for the HSDPA (High-Speed Downlink Packet Access), a new protocol for mobile telephone data transmission, and the other for transmitting and receiving radio wave for emergency call. Using the transparent electrically conductive film formation technology, the transparent antennas are to be mounted on the windshield of a vehicle. "The development of transparent antenna represents a step forward for the advancement of the next-generation automotive electronic technology," said Seong-woo Kim, a senior researcher at the Hyundai-Kia Group.
Three Professors Selected as IEEE Fellows
Three Korea Advanced Institute of Science and Technology (KAIST)’s professors, Ju-Jang Lee, Yong-Hee Lee, and Hoi-Jun Yoo, were selected as a part of the 2008 Institute of Electrical and Electronics Engineers, Inc (IEEE)’s “Fellows.” A Fellow is the highest level of membership given only to those “with an extraordinary record of accomplishments” in their field of study. Although some IEEE memberships can be gained freely by all, the Fellow status is bestowed only by the IEEE Board of Directors. Professor Ju-Jang Lee was awarded the Fellow status “for contributions to intelligent robust control and robotics.” Robust control is a system’s stable maintenance under many inputs in a dynamic environment. A part of KAIST’s Electrical Engineering Department, Professor Ju-Jang Lee has conducted successful research in these fields, and has published 538 papers. He also holds many patents in and outside of the country, and is the General Chair for two upcoming IEEE conferences in 2008 and 2009. Professor Yong-Hee Lee of KAIST’s Physics Department was recognized for his “contributions to photonic devices based upon vertical cavity surface emitting lasers and photonic crystals.” Photonic devices are those that allow the practical use of photons, and photon crystals are structures that affect the motion of photons. Professor Yong-Hee Lee is an expert in the field of Photonics and his works have been cited over 2500 times. He is also an outstanding speaker, giving over 30 lectures in front of international audiences in the past 5 years, and receiving The Distinguished Lecturer’s Award from IEEE. Professor Hoi-Jun Yoo was granted the prestigious Fellow status for his “contributions to low-power and high-speed VLSI design.” VLSI stands for ‘very large scale integration’ and refers to the skill for packing a huge number of semiconductors on an integrated circuit. Professor Lee’s Fellow status is noteworthy in that he studied, worked, and researched solely in Korea. He is also the youngest of the three KAIST professors to be granted membership in the class of 2008 Fellowship. IEEE also recognized Professor Yoo as the most frequent publisher during the past 8 years. IEEE, originally concentrating on Electric Engineering, has now branched into many related fields. It is a nonprofit organization, and its aim is to be the world"s leading professional association for the advancement of technology.

Professor Seong-Ihl Woo Develops New High-Speed Research Method
Professor Seong-Ihl Woo Develops New High-Speed Research Method Reduce research periods and expenses for thin film materials several ten times Posted on the online version of Proceedings of National Academy of Sciences of the United States of America (PNAS) on January 9 A team led by Seong-Ihl Woo, a professor of KAIST Department of Chemical & Biomolecular Engineering and the director of the Center for Ultramicrochemical Process Systems, has developed a high-speed research method that can maximize research performances and posted the relevant contents on the online version of Proceedings of National Academy of Sciences of the United States of America (PNAS), a distinguished scientific journal, on January 9, 2007. Professor Woo’s team has developed a high-speed research method that can fabricate several tens or several thousands of thin films with different compositions (mixing ratio) at the same time and carry out structural analysis and performance evaluation more than ten times faster and accurately, which leads to the shortening of the research processes of thin film materials. This is an epoch-making method that can reduce research periods and expenses several ten times or more, compared to the previous methods. The qualities of final products of electronic materials, displays, and semi-conductors depend on the features of thin film materials. Averagely, it takes about two weeks or longer to fabricate a functional thin film and analyze and evaluate its performances. In order to fabricate thin film materials in need successfully, more than several thousand times of tests are required. The existing thin film-fabricating equipment is expensive one demanding high-degree vacuum, such as chemical vapor deposition, sputtering, physical vapor deposition, laser evaporation, and so on. In order to fabricate thin films of various compositions with this equipment, a several million won-worth target (solid-state raw material) and precursors (volatile organic metal compound) pricing several hundreds won per gram are required. Therefore, huge amount of experiment expense is demanded for fabrication of several ten thousands of thin films with various compositions. Professor Woo’s team has developed ‘combinatorial droplet chemical deposition’ equipment, which does not demand high-degree vacuum and is automated by computers and robots, by using a new high-speed research measure. The equipment is priced at about 1/5 of the existing equipment and easy for maintenance. This equipment uses cheap reagents, instead of expensive raw materials. Reagents necessary to form required compositions are dissolved in water or proper solvents, and then applied by high frequencies to make several micrometer-scaled droplets (fine liquid droplet). Theses droplets are moved by nitrogen and dropped onto a substrate, which is to be fabricated into a thin film, and then subsequent thermal treatment is applied to the substrate to fabricate a thin film of required composition. At this moment, several tens or several hundreds of thin films with various compositions can be fabricated at the same time by reducing the size of thin film specimens into millimeter scale with the use of shade mask and adjusting vaporization time with masks, the moving speed of which can be adjusted. The expenses for materials necessary for the fabrication of thin films with this equipment amount to several ten thousands won per 100 grams, which is in the range of 1/100 and 1/10 of the previous methods, and the research period can be shortened into one of several tenth. “If this new method is applied to the development of elements in the fields of core energy, material and health, which have not been discovered by the existing research methods so far, as well as researches in thin film material field, substantial effects will be brought,” said Professor Woo. ‘Combinatorial droplet chemical vaporization’ equipment is pending a domestic patent application and international patent applications at Japan and Germany. This equipment will be produced by order and provided to general researchers.
