Il-Koo Yoon

Professor Il-Koo Yoon's research lab specializes in advanced optoelectronic devices and integrated circuit technologies, with a strong focus on photodiodes, embedded passive components in multichip modules, and process variability in nanoscale transistors. The lab conducts fundamental and applied research on device physics, circuit modeling, and high-frequency performance optimization using advanced simulation and measurement techniques such as impedance field methods and S-parameter characterization. Key research directions include the design and optimization of high-performance photodetectors, the development of accurate equivalent circuit models for embedded passive components using genetic algorithms and Levenberg-Marquardt methods, and the analysis of process-induced variability in 14 nm node junctionless FinFETs. The lab bridges the gap between device physics, circuit design, and system-level performance in next-generation semiconductor technologies.
