Abstract
Description
Claims (3)
- 반도체 소자의 실리콘 질화막 식각 방법에 있어서, 식각 속도를 증가시키며, 폴리머의 생성을 감소시키기 위하여 불화탄소계의 가스에 산화질소(N2O) 가스가 첨가된 식각 가스를 이용하여 실리콘 질화막을 식각하는 것을 특징으로 하는 반도체 소자의 실리콘 질화막 식각 방법.
- 제1항에 있어서, 상기 불화탄소 계의 가스는 CF4인 것을 특징으로 하는 반도체 소자의 실리콘 질화막 식각 방법.
- 제1항에 있어서, 상기 불화탄소 계의 가스는 CHF3인 것을 특징으로 하는 반도체 소자의 실리콘 질화막 식각 방법.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
