Claims (4)
- 반도체기판상에 패드산화막과 질화막을 형성하고 소정 부분을 제거하여 필드부분을 한정하는 공정과, 상기 패드산화막과 질화막의 측면에 제1측벽을 형성하고, 이 제1측벽의 측면에 제2측벽을 형성하는 공정과, 상기 제1측벽과 제2측벽을 마스크로하여 반도체기판의 상기 필드부분을 소정 깊이로 식각하여 홈을 형성하고, 상기 제2측벽을 제거하는 공정과, 상기 홈과 상기 제2측벽이 제거되어 노출된 부분의 반도체기판을 산화하여 소자분리영역을 한정하는 공정과, 상기 질화막, 패드산화막 및 제1측벽 제거하여 반도체기판의 활성 영역을 노출시키는 공정을 구비하는 반도체장치의 소자분리영역 형성방법.
- 제1항에 있어서, 상기 제2측벽은 산화막 또는 다결정실리콘으로 형성하는 반도체장치의 소자분리영역 형성방법.
- 제2항에 있어서, 상기 제2측벽은 200∼1000A의 두께로 형성하는 반도체장치의 소자분리영역 형성방법.
- 제1항에 있어서, 상기 홈을 500∼3000A의 깊이로 이방성 식각하는 반도체장치의 소자분리영역 형성방법.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
