Our department’s professor Byung Jin Choi’s research team has developed a key technology for power efficiency of next generation semiconductor devices. The technology can coat a germanium wafer with an insulating film which can minimize current leak loss. Traditional FINFET and GAA fabrications can simultaneously reduce the price and increase the performance but slows down the electron-hole speeds due to small device dimensions. Professor Cho’s team has developed a technology which can overcome these obstacles.

Kihyoen Ahn from the KSIA mentioned that it is a key technology for overcoming the slowing down development of device minituarization.

Professor Cho’s team has been awarded the best paper award at the 26^th Korea Semiconductor Conference for the development.

The research was conducted under the Samsung Electronics, SK Hynix, MOTIE supported ‘Future Semiconductor Device Technology Development Project’.

Paper Title: A study on Military Surveillance and Reconnaissance Systems based on Multimodal Deep Learning Robust against Adversarial Attacks

Our department’s professor Hyunchul Shim’s lab has won the MSIT AI Grand Challenge Competition Control Intelligence Part for the 2^nd year in a row.

This year’s competition was based on how AI can solve various problems that will emerge from the AI based future. The challenge was to set an idea about how to use AI for responding to people’s life in various areas and social issues.

Composed of 4 major areas, professor Shim’s team applied to track 4, where a total of 5 teams applied. Professor Shim’s team used the idea of how to safely use drones to deliver supplies and goods to people.

Winning for the 2^nd year in a row, Professor Shim’s team used only 100% self developed technologies (accurate positioning, high speed flight control) for the competition. Winning the competition again this year, the group will be funded a total of 2.4 billion KW which is similar to the DARPA challenge award prize. Along with the development of AI, professor Shim said that his team will further develop inside drone flight, unmanned civilian aircraft, autonomous vehicles, delivery robots and other vehicle related AI technologies.

Once again we congratulate professor Shim’s team for the reward.

Our department’s professor Junil Choi’s lab has achieved the best and excellent paper award at the 12^th ICT paper competition. The 12^th ICT paper competition supported by Etnews, Webcash Group, and KSFC has awarded the best paper award to Ph.D candidates Hwanjin Kim (1^st author), Sucheol Kim, Hyeongtaek Lee and the excellent paper award Ph.D candidate In-soo Kim.

A total of 5,000,000 and 2,000,000 KW are rewarded to the best and excellent paper.

The ICT paper competition marking its 12^th anniversary this year evaluates and rewards various papers based on semiconductor, communications, AI, IoT and other ICT related fields. The competition is open for South Korean students attending domestic universities and graduates schools.

The research team of Professor Jae-Woong Jeong has developed a technology that can produce optogenetic neural probes using 3D printing through joint research with a research team at Washington University School of Medicine in St. Louis.

This research, in which Ph.D. student Ju-Hyun Lee participated as the first author, was published in the international journal ‘Advanced Functional Materials’ on November 11th edition as a back cover. (Title: Rapidly Customizable, Scalable 3D-Printed Wireless Optogenetic Probes for Versatile Applications in Neuroscience)

In brain science and neuroscience research, optogenetics technology that precisely controls neural circuits through light is getting more attention recently. Neural probes are needed to transmit light to the deep brain. For brain research, different optimized designs are required depending on the target animal and the location of the target neural circuit. However, in general, semiconductor processes used to manufacture neural probes have limitations in that design modification is not easy, and a lot of cost and time is consumed each time a probe with a new design is developed.

The research team has overcome this limitation by using a 3D printer. Through SLA-based 3D printing, the team implemented a neural probe with the thickness of a hair. As a result, the optoelectronic probe with micro LEDs can be manufactured at the cost of less than $1 per piece, which is more than 50 times cheaper than commercial neural probes. This paved the way for providing highly affordable neural probes to the neuroscience community.

In addition, the research team proved the long-term biocompatibility and durability of the 3D-printed probe through animal experiments and verified its functionality by controlling the brain neural circuits of mice that move freely through optogenetic stimulation.

This technology enables rapid design and design modification of probes through CAD software, allowing rapid production of devices of various lengths and shapes. Not only 1D structure with one stimulation point, but also complex neural probes with 2D and 3D structures can be implemented, so it can be used for the study of complex neural circuits. The developed 3D printing process makes it easy to develop probes optimized for specific research purposes and can significantly shorten production time and cost, and is expected to contribute to the acceleration of neuroscience research.
