Abstract: 본 발명은 얇은 두께를 갖는 게이트 산화막 형성 방법에 관한 것이다. 게이트 산화막의 특성 개선을 위해 실리콘 기판에 질소 이온을 주입한다. 이후, 얇은 산화막을 형성하고 열처리 과정을 진행하여 기판 내부에 주입된 질소 이온들이 기판과 산화막의 계면에 모이도록 유도한다. 따라서, 게이트 산화막을 형성하기 위해 얇은 산화막을 추가 성장시키면 질소 이온에 의해 성장 속도가 저하되므로, 얇은 게이트 산화막을 형성할 수 있을 뿐만 아니라 두께 조절도 용이하게 할 수 있다. 또한, 열처리에 의해 질소 이온 주입시 발생된 기판 결함도 치유할 수 있다.
