My research focused on interfacial reliability in semiconductor packaging, mechanical properties of thin films, and fully freestanding nanofilms. The goal is to map the interfacial adhesion energy in Front-End-of-Line (FEOL) and Back-End-of-Line (BEOL) structures and manufacture transferrable advanced freestanding devices.
I have been a Ph.D. student in Professor Taek-Soo Kim's group (Advanced Packaging and Thin Film Laboratory) at the department of mechanical engineering, KAIST, since 2022.
