Abstract

박막 트랜지스터를 제조할때, 게이트 모서리에 발생되는 브릿지를 제거하기 위해, 습식식각 및 습식산화를 적용하여, 박막 트랜지스터의 채널 폴리실리콘의 잔유물을 제거하여, 박막 트랜지스터의 특성 및 균일도를 향상시킨다.In manufacturing the thin film transistor, wet etching and wet oxidation are applied to remove the bridges generated at the edges of the gate, thereby removing the residue of the channel polysilicon of the thin film transistor, thereby improving the characteristics and uniformity of the thin film transistor.
