Work History
High-throughput Experiment Driven Development of Next Generation Semiconductor Interconnects
Sungkyunkwan University & Samsung Electronics
02.2023 - Current
- Collaborated with the Samsung R&D team to develop Cu-based next-generation interconnect alloys, including Co and Ru alloys.
- Conducted high-throughput experiments to deposit thin film alloys on silicon wafers using sputtering (PVD), and used XRD, TEM, and a 4-point probe for evaluating properties such as resistivity and electromigration resistance.
- Investigated the alloying effects on grain boundary diffusion and enhanced electromigration resistance, contributing to the identification of alloys with lower resistance for advanced semiconductor devices.
- Discovered specific Co-based alloy compositions that simultaneously achieved lower electrical resistivity and superior electromigration resistance compared to pure Cu and Co.
Machine Learning Analysis of High-k Metal Gate Semiconductor Process
Sungkyunkwan University & Samsung Electronics
02.2023 - Current
- Published a first-author research paper on optimization of high-k metal gate peripheral transistor processes. (doi.org/10.1063/5.0191100)
- Engineered advanced HfSiON-based high-k/metal gate stacks with optimized interlayer nitridation and metal work-function tuning to enhance DRAM transistor performance.
- Conducted material-level optimization of high-k/metal gate stacks, including interlayer nitridation and HfSiON integration, achieving improved reliability and reduced leakage in DRAM devices.
- Developed and optimized deposition/nitridation processes for high-k/metal gate stacks (HfSiON, TiN/Al) to address interface trap density and threshold voltage stability in advanced DRAM transistors.
- Implemented AI analysis techniques including anomaly detection, inverse design, and explainable AI (XAI) for device process optimization through MES.
