Winner of the Excellent Design and Excellent Poster Awardsat the 27th Korean Conference on Semiconductors Professor Choi Woo Young's research team won the Excellent Design Award and the Excellent Poster Award at the 27th Korean Conference on Semiconductors (KCS) held in Gangwon-do in February. This conference, which is a major academic conference in the field of semiconductors, was arranged to discuss semiconductor technology innovation that will lead the next generation of major ICT convergence technologies and directions for the future. Kwon Hyug Su, who received the excellent design award, is in doctoral program in the Department of Electronic Engineering (Advisor: Prof. Choi Woo Young). He was the first in the world to experimentally implement the single tile operation of CMOS-NEM reconfigurable logic device/circuit using a nanoelectromechanical (NEM) device. The CMOS-NEM reconfigurable logic device/circuit presented through this study was implemented based on 65 nm process technology, and the NEM device responsible for signal change was implemented in the post-process wiring section. This device/circuit is expected to have a chip density 4.6 times higher, an operating frequency 2.3 times higher, and a power consumption 9.3 times lower than a conventional CMOS device-only circuit. With higher speed and lower power consumption equivalent to the ASIC (Application Specific Integrated Circuit) level, it is also expected to make a great contribution to implementing a field-programmable gate array (FPGA) with microprocessor-level operational flexibility. This technology, implemented for the first time in the world, has the characteristics of a source technology that can change the paradigm of semiconductor technology, not just the field of reconfigurable logic device/circuit technology. In the short term, it is possible to expand into the field of ultra-low-power memory-in-logic and analog computing, and ultimately, it is expected to enable the emergence of ultra-low-power three-dimensional neuro-simulation semiconductor chips. ▶Thesis Title: Monolithic three-dimensional (M3D) CMOS- Nanoelectromechanical (NEM) Single-tile Reconfigurable Logic (RL)▶Authors: Kwon Hyug Su (First author), Ph.D. candidate, and Professor Choi Woo Young (Second author) In the same competition, Kang Min Hee, a master's student in Electronic Engineering (Advisor: Prof. Choi Woo Young) was awarded the Outstanding Poster Award in recognition of its contribution to improving the reliability of NEM by alleviating the stress of NEM through selection line optimization. The NEM of the selection line optimization structure presented this time was verified for its efficacy through the finite element method, and showed that the stress concentrated on the anchor part of the NEM was reduced as the selection line was reduced. In addition, the optimal selection line length was demonstrated, showing the change in NEM pull-in voltage that occurs while reducing the selection line. The NEM of the selection line optimization proposed by the research team is expected to reduce stress by over 40% compared to the existing structure. Through this, it is expected that the proposed structure will greatly contribute to improving the reliability of CMOS-NEM hybrid circuits. ▶Thesis Title: Selection Line Optimization of Nanoelectromechanical (NEM) Memory Switches for Stress Relief▶Authors: Kang Min Hee, Master's candidate (First author), Professor Choi Woo Young (second author)

The joint research team led by Prof. Song Tai-Kyong and prof. Chang Jin-Ho from the Department of Electronic Engineering at Sogang University developed a world-first convergence imaging technology to innovatively improve the accuracy of sentinel lymph node biopsy guidance, which is used to detect breast carcinoma metastasis. Through preclinical testing, the effects and availability were technically proven for clinical usage. The outcome of the research was posted in the March 22nd issue of Scientific Reports, an affiliated journal of Nature (https://www.nature.com/articles/srep45008).If this equipment for convergence imaging diagnosis, which is being developed at this time, is commercialized, the limitations will be overcome for treatment and diagnosis using a single imaging device. For instance, preclinical testing has demonstrated that the precise identification of the sentinel lymph node (the primary lymph node that a cancer cell passes through in the case of metastasis) and the accuracy of biopsy guidance can be enhanced.Prof. Song said, “Thanks to this technology, ultrasonic and photo-acoustic images are now available ahead of biopsy guidance, and doctors can reconfirm during the biopsy procedure whether the lymph node to be removed is the signal lymphatic gland or not, using the fluorescent images.” He added, “This enables fast and accurate biopsy procedures and a minimum incision on the part to be used for the biopsy. It is expected that more accurate decisions on carcinoma metastasis and biopsy procedures will minimize the side effects and complications that a patient must endure.”It is also projected that the technology will be utilized for clinical applications in a variety of ways, such as through convergence image guidance surgeries aimed at enhancing the accuracy of cancer tumor removal.

Prof. Jang Jin-ho’s Research Team at Sogang Institute Advanced TechnologySelected for ICT Creative Task at Samsung Science & Technology Projectto Receive Total of KRW 1.4 Billion for 4 Years Prof. Jang Jin-ho’s research team at Sogang Institute Advanced Technology (SIAT) at Sogang University has finally been selected for an ICT creative task at Samsung Science & Technology Project that provides support in the latter half of 2017. The Samsung Science & Technology Project which started in 2013 is a program to select excellent tasks three times a year in three areas of research of fundamental science, materials technology, and ICT, thereby supporting and nurturing future technologies in the Republic of Korea by providing a total fund of KRW 1 trillion 500 billion for 10 years. For the latter half of 2017, 14 tasks for the fundamental science and 23 tasks for the materials technology and ICT have been selected including the task of “development of ultrasound-assisted confocal microscopy for deep tissue imaging” by Prof. Jang Jin-ho, and a total of KRW 53.1 billion will be provided. The selected task of Prof. Jang is to develop an original technology to settle the issue of a low image depth which is an inborn limitation of the conventional confocal microscope, aiming to develop a technology to increase an image depth of a confocal microscope without a lowered image resolution by using ultrasound wave. A confocal microscope is a device that focuses and irradiates light to a living tissue and that uses a reflected light signal, thereby providing structure information of a microtissue such as a cell with a high-resolution, high-contrast image. Currently, the confocal microscope is the most broadly used as a three-dimensional high-resolution imaging technique for life science researches and disease diagnosis including images of cancer, brain tissues, etc. However, though a high-resolution, high-contrast image provided by the confocal microscope is available only at a depth in which light can be focused, the depth for focusing light is only hundreds of micrometers due to optical scattering in a living tissue. Thus, it is difficult to image a tissue in a deeper part. To resolve the issue, Prof. Jang Jin-ho’s research team will develop an original technology for a confocal microscope, a technique that is expected to increase a depth of light penetration by temporarily changing characteristics of a medium to minimize optical scattering in the medium in which the light proceeds, using an ultrasound energy recently developed by the team. The proposed technology is an original technology with a new concept, which can not only remarkably broaden an application area of a confocal microscope that has limitations triggered by a low image depth but also expand the application area of the conventional optical image and treatment technologies that have limitations in use because of a low depth of light focusing. Thus, the technology has a very great impact to satisfy unmet clinical needs. If the technology is commercialized, one can easily enter into and expand a share in the existing optical image market, an area that is mostly occupied by overseas technological leading companies, thereby creating a new market and leading the relevant industries in the whole world.
