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.

Singer Janghoon Kim Donates Development Fund to KAIST
Singer Janghoon Kim Donates Development Fund to KAIST - Generously donates part of earnings from his concert where HUBO performed for development of science - Opportunity for activation of science culture through encounter between science and culture Singer Janghoon Kim donated 50 million won from his concert earnings for KAIST development fund. Singer Kim visited KAIST on January 16 (Tue) and donated the development fund at the joint lecture room in KAIST Mechanical Engineering B/D. Singer Kim had a concert at the end of the last year where he performed with ‘HUBO’ and ‘Albert HUBO’, human-like robots of KAIST HUBO center. Singer Kim made a donation to express his gratitude to KAIST Professor Joonho Oh and his research team, who assisted his concert actively to allow HUBO to join the concert in spite of technical difficulties and research obstacles. “Although HUBO has performed various activities so far, it is the first time to make a successful performance with a singer on a stage. Honestly, I hesitated a lot to allow HUBO to join Kim’s concert due to safety problems etc., but I was so impressed by Kim’s interest and passion for science, and thus decided HUBO’s joining the concert. This is the first case how robots can exchange with public cultures. I wish this case will be a momentum to activate science culture and make people feel closer to science,” Professor Oh said. The donation will be spent partly as KAIST development fund (20 million won) and partly on the publicity of science and technology via HUBO (30 million won).

Final competition of 'UFC' contest
Final competition of ‘UFC’ contest Joint university team D-M2 won first prize The final winner of ‘the 2nd Ubiquitous Fashionable Computer (UFC) contest‘, co-hosted by KAIST and the Korean Society for Next-Generation Computing (KSNGC), was determined. At the final competition of November 17 among 9 qualified teams, the first prize went to D-M2, composed of students from Seokyeong University, Kookmin University, Hongik University, and Sungshin Women’s University. D-M2 manufactured a work utilizing a user’s motion information by applying motion capture technologies to UFC. Particularly, the work gained a high score at the item of the functional perfection by controlling the robot according to a user’s motion. The gold prize went to the smart jacket by Jjik-eo-cha-ki (Kwangwoon University and Duksung Women’s University). The smart jacket is embedded with an intelligent clothes function in terms of checking a user’s status in a real-time basis and delivering it to a doctor, etc. The silver and bronze prizes went to Samsung Software Membership (SSM) and Hanse University, respectively. SSM manufactured a training suit with sensors for grasping the movement of each articulation of a user built-in, and Hanse University developed a system enabling blinders to get a voice service of general documents or books regardless of time and place. The participants composed of university students or graduate students have passed the severe qualifying contest through the examination of written plan and presentation of last April and manufactured creative works that realize the fusion of IT technologies and fashion. At the contest, that fact that all winners of the first, gold, and silver prizes were the members of SSM gained more attention. UFC is a new field that pursuits the enhancement of computer technologies and the creation of fashion simultaneously by fusing IT technologies and fashions. UFC is a one-step advanced field of the existing wearable computer and an important cutting-edge field that leads a computer industry in the era of ubiquitous. “The level of the works exhibited was higher than I’d expected and the cooperation between the departments of Closing Textile and Electronics appeared to be so positive, which made me expect more brilliant future of the next-generation computing industry,” said Hoijoon You, Co-chairman of the contest and professor of the department of Electrical Engineering.
