Description
Claims (3)
- 네킹 형성 단계를 포함하며, 사각기둥 형태의 종결정을 이용하는 실리콘 단결정 성장에 대한 평가 방법으로서,상기 실리콘 단결정 성장 방법으로 얻은 샘플에서 네킹 부위를 15분 이상 라이트(Wright) 에칭하는 단계; 및상기 네킹 부위에 있어서 상기 종결정의 4개의 옆면 중 실리콘 단결정 성장 중에 발생하는 볼록한 형태의 긴 노드(node)가 없는 면을 광학현미경을 이용하여 관찰하되, 피트(pit) 형상이 사라지는 지점을 슬립 전위가 사라지는 지점으로 정하여 슬립 전위 제거를 위한 네킹 길이를 결정하는 단계를 포함하는 것을 특징으로 하는 평가 방법.
- 제1항에 있어서, 상기 피트 형상을 에칭에 의한 미세 홀(hole) 및 잔존하는 오염 물질과 구분하기 위하여, 상기 광학 현미경의 초점심도를 조절하여 초점 조절시 뚜렷하게 잔상이 남는 것을 피트 형상으로 분류하는 것을 특징으로 하는 평가 방법.
