Abstract
Description
상기 제1 게이트산화막 및 산질화막을 형성하는 단계는, 상기 질화막이 형성된 반도체기판에 대해 산화 공정을 실시하여 상기 커패시터영역에는 산질화막이, 그외의 영역에는 산화막이 형성되도록 하는 단계와, 상기 고전압영역 이외의 영역의 상기 산화막을 제거하는 단계로 이루어질 수 있다.
상기 제1 게이트산화막 및 산질화막을 형성하는 단계 후에, 상기 제1 게이트산화막 및 산질화막이 형성된 반도체기판을 암모니아 계열의 세정액을 사용하여 세정하는 단계를 더 포함할 수 있다.
상기 폴리실리콘막이 형성된 반도체기판 상의 결과물을 패터닝하는 단계 후, 상기 제1 및 제2 게이트전극과 상기 커패시터의 측벽에 절연막 스페이서를 형성하는 단계를 더 포함할 수 있다.
