Abstract
Description
Claims (4)
- 반도체기판에 소자형성영역과 소자분리영역을 정의하기 위한 소정의 포토레지스트 패턴을 형성하는 단계; 상기 소자분리영역의 반도체기판을 산화시켜 소정두께의 산화막을 형성하는 단계; 상기 포토레지스트 패턴의 둘레를 따라 상기 반도체기판에 대하여 식각선택비를 갖는 스페이서를 형성하는 단계; 상기 포토레지스트 패턴 및 스페이서를 식각마스크로 적용하여 상기 반도체기판 내에 소정 깊이의 트렌치를 형성하는 단계; 및 상기 트렌치에 절연물질을 채우는 단계를 구비하여 이루어진 것을 특징으로 하는 트렌치 소자분리방법.
- 제1항에 있어서, 상기 산화막의 두께는 100Å∼500Å 정도인 것을 특징으로 하는 트렌치 소자분리방법.
- 제2항에 있어서, 상기 스페이서는 고온산화막(HTO)이나 질화막으로 이루어진 것을 특징으로 하는 트렌치 소자분리방법.
- 제3항에 있어서, 상기 트렌치는, 그 하부 사이즈가 그 상부 오프닝 사이즈보다 작은 슬로프를 갖도록 식각되는 것을 특징으로 하는 트렌치 소자분리방법.※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.
