Abstract
소형의 3-5족 반도체 구조체를 제조할 수 있다. 3-5족 반도체 재료상에 질화 실리콘 막을 형성하고, 질화 실리콘 막 상에 알루미늄 함유의 절연막을 형성한다. 알루미늄 함유의 절연막 상에 실리콘 및 산소 함유의 다른 절연막을 형성한다. 알루미늄 함유의 절연막은 고 전력 반응 이온 에칭으로 실리콘 및 산소 함유의 절연막의 에칭에 대한 에칭 억제용으로 작용한다. 알루미늄 함유의 절연막은 질화 실리콘 막을 실제로 에칭하지 않는 습윤 부식제로 에칭될 수 있다. 질화 실리콘 막과, 실리콘 및 산소 함유의 절연막 사이에 알루미늄 함유의 절연막을 형성함으로써, 고 전력 반응 이온 에칭에 대한 노출에 의한 반도체 재료의 표면 손상을 방지할 수 있다.
