Abstract: 본 발명은 반도체 메모리 소자에서 선택적 에피택셜 성장을 이용한 소자 분리막 형성공정을 개시한다. 개시된 본 발명은 실리콘 기판 상부에 패드 산화막과 하드 마스크 질화막을 차례로 형성하는 단계; 소자분리 예정 영역을 한정하는 감광막 패턴을 형성하는 단계; 상기 감광막 패턴에 의해 트랜치를 형성하는 단계; 상기 트랜치의 양 측벽을 염산 또는 수소기체를 이용하여 소정부분 식각하는 단계; 열산화 공정을 이용하여 식각된 트랜치의 양측면이 만회되도록 산화막을 형성하는 단계; 상기 하드 마스크 질화막을 이용한 반응 이온 식각공정을 통하여 상기 트랜치내의 산화막을 직진 식각하는 단계; 상기 직진 식각된 트랜치 내에 잔류된 유기물과 산화막을 제거하는 클리닝 공정을 수행하는 단계; 및  클리닝 공정이 수행된 트랜치 내에서 적당한 높이로 선택적으로 에피택셜 층을 성장시키는 단계를 포함하여 구성하는 것을 특징으로 한다.
