    Jeonghyo Lee, a student in the Integrated Program at POSTECH’s Department of Electrical Engineering (advisor: Prof. Wonbin Hong), received the TICRA Travel Grant at the 2024 IEEE International Symposium on Antennas and Propagation and ITNC-USNC-URSI Radio Science Meeting (IEEE AP-S/URSI). The TICRA Travel Grant is awarded by the TICRA Foundation, which leads education and research in the global electromagnetic technology field. Only eight recipients worldwide are selected to receive a $1,000 travel scholarship, and it is known to be particularly difficult for graduate students to win this prestigious award, as it is open to researchers from all career stages.

    Jeonghyo Lee is conducting research on “Independent, Concurrent Dual-Harmonic Frequencies Operation of Overlapped Spatial-Temporal Phased Array using Dual-Functional Radiator.” This study proposes, for the first time, the operation of dual-resonant frequencies in a fully overlapped spatial-temporal phased array using a single module, and it has demonstrated superior performance compared to other research presented globally. This research was previously recognized with an Honorable Mention at the same conference, and now with the TICRA Travel Grant, Lee has achieved a remarkable global accomplishment.

  • Professor Rokhyeon Baek from POSTECH's Department of Electrical Engineering has been invited to give a presentation at the International Electron Device Meeting (IEDM).

    Professor Rokhyeon Baek from POSTECH’s Department of Electrical Engineering was invited to give a presentation at the IEEE International Electron Device Meeting (IEDM) on December 11, 2024, as part of the Focus session on “Leading Semiconductor Products and Advanced Packaging.” This session is designed around the most prominent topics of the year, selected by the organizing committee, with suitable speakers invited from around the world. Notably, POSTECH was the only academic institution among the speakers, alongside industry giants such as NVIDIA, AMD, Qualcomm, TSMC, Intel, TEL, and IBM.

    In his presentation, Professor Baek and his research team provided a roadmap for cutting-edge logic technologies, including Forksheet and Complementary devices, as well as three-dimensional wafer backside technologies, which are applicable to the next-generation angstrom technology nodes beyond the nanoscale. They used quantitative metrics and integrated analysis to present the advancements in these technologies.

    The IEDM, celebrating its 70th anniversary this year, is considered one of the most prestigious conferences in the semiconductor device and process fields, alongside the Symposia on VLSI Technology and Circuit. The conference is held annually in early December in San Francisco, USA.

  • Professor Seun Shin's research team received the Best Paper Award from the Power Electronics Society.

    Ph.D. student Jonghoon Kim from POSTECH’s Semiconductor Graduate School and Professor Seun Shin’s Power Management and Integrated Circuit Systems Design Laboratory (PICTUS) received the Best Paper Award at the 2025 Fall Conference of the Power Electronics Society of Korea. Their paper, titled “Gate Drive Circuit for GaN Power Semiconductors with Built-in Overcurrent and Overvoltage Protection”, was recognized for its contribution to the field.

    The paper proposes a gate drive circuit design for high-speed and highly reliable power conversion using wide bandgap (WBG) semiconductor materials, including gallium nitride (GaN). The proposed GaN-specific gate drive circuit uses a high-speed gate drive IC, achieving operation up to 13.56 MHz, with an overcurrent protection time of 120 ns and a 45% reduction in gate voltage peaks. This innovation is expected to contribute to the miniaturization and improved reliability of devices in various applications such as consumer electronics, electric vehicles, and clean energy systems.
