Description
Claims (8)
- 반도체장치의 인접한 소자를 상호분리하는데 있어서, 실리콘기판위에 완충산화막 및 질화막을 순차로 적층형성하여 필드영역을 개구하는 공정 ; 채널저지이온 및 실리콘이온(Si+)을 필드영역에 이온 주입시키는 공정 ; 이어서 상기 필드영역을 산화하여 필드산화막을 형성시킨다음, 상기 적층막을 제거하는 공정을 구비하여 이루어진 것을 특징으로 하는 반도체장치의 소자분리방법.
- 제1항에 있어서, 채널저지이온 및 실리콘이온을 필드영역에 이온주입시키는데 있어서 채널저지이온 주입공정후, 실리콘이온 주입공정이 수행되는 것을 특징으로 하는 반도체 장치의 소자분리방법.
- 제2항에 있어서, 실리콘이온 주입공정후에 채널저지이온을 필드영역에 주입시키는 것을 특징으로 하는 반도체장치의 소자분리방법.
- 제2항 및 제3항의 어느 한항에 있어서 실리콘이온 주입된 필드영역은 액티브 영역에 비해 실리콘기판이 고농도 인것을 특징으로 하는 반도체장치의 소자분리방법.
- 제2항 및 제3항의 어느한항에 있어서 상기 실리콘이온(Si+)의 주입농도는 1.0E16Cm-2∼1.0E20Cm-2이상인 것을 특징으로 하는 반도체장치의 소자분리방법.
- 반도체장치의 실리콘기판에 있어서 일정부분의 산화막을 다른 부위에 비해 더 두껍게 성장시키기는 위하여 상기 실리콘기판의 일정부분에 실리콘이온(Si+)을 주입하여 산화시키는 것을 특징으로 하는 실리콘 산화방법.
- 제6항에 있어서, 상기 실리콘기판 대신에 폴리실리콘층을 이용하여 일정부분의 산화막 두께를 두껍게 형성시키는 것을 특징으로 하는 폴리실리콘 산화 방법.
- 제6항 및 제7항에 있어서 상기 실리콘기판 및 폴리실리콘층 대신 비정질 실리콘층을 이용하여 일정부분의 막을 두껍게 산화시키는 것을 특징으로 하는 비정질 실리콘 산화방법.
