Abstract
절연성을 갖는 기판상에 형성된, 결정성을 갖는 실리콘 반도체 박막을 이용한 활성영역을 구비하는 반도체장치의 제조방법이 개시된다. 결정성 실리콘 반도체막은, 하층 비정길 실리콘 반도체막에 결정화를 촉진하는 촉매원소를 도입한 후에 가열처리함으로써 얻어진다. 또한, 그 후에, 얻어진 하층 결정설 실리콘 반도체막상에 비정질 실리콘 반도체막을 제공하여 가열처리를 실시하고, 상층 결정성 실리콘 반도체막을 얻는다. 이 상층 결정성 실리콘 반도체막을 그 후에 제거된다. 이공정에 의해, 하층 결정성 실리콘 반도체막에 잔류를 촉매원소가 상층 경정성 실리콘 반도체막내로 이동하여, 하층 결정성 실리콘 반도체막중의 촉매원소의 농도가 감소된다.
