Summary
I am a 2nd year Ph.D. student at National Taiwan University. I have worked as a Senior Engineer in the R&D division with almost 3 years of working experience in the field of 'Thin-Film Development.' My current research area consists of fabrication, characterization, and reliability (PBS, NBIS, etc.) study of planar and gate-all-around (GAA) TFTs using amorphous oxide semiconductors (IGZO, In2O3, etc.) as the channel material
