Claims (6)
- 진공챔버 내에서 웨이퍼를 지지하고, 이송하기 위한 스테이지;상기 진공챔버의 제 1 윈도우를 통해 주입되는 레이저 광을 발생시키는 광원부;상기 진공챔버 내에 존재하고, 상기 광원부에서 발생된 레이저 광의 진행 방향을 변경하는 반사미러;상기 웨이퍼 검사면에서 산란된 레이저 광을 이용하여 디펙트를 검출하는 광학현미경;상기 검출된 디펙트를 고배율로 리뷰하기 위한 주사전자현미경; 및상기 광원부에 연결되고, 상기 광원부를 회전 및 이동시키는 얼라인 유닛을 포함하되,상기 얼라인 유닛은 상기 산란된 레이저 광이 상기 진공챔버의 제 2 윈도우를 통해 상기 광학현미경의 시야범위에 들어가도록 하는 것을 특징으로 하는 웨이퍼 디펙트 검사장치.
- 삭제
- 제 1 항에 있어서,상기 광원부는 상기 레이저 광이 상기 제 1 윈도우를 통해 수직하게 상기 진 공챔버 내로 입사하도록 배치된 것을 특징으로 하는 웨이퍼 디펙트 검사장치.
- 제 1 항에 있어서,상기 반사미러는 상기 웨이퍼 표면에 입사하는 레이저 광이 8 내지 16도의 경사각을 갖도록 배치된 것을 특징으로 하는 웨이퍼 디펙트 검사장치.
- 검사장치를 통해 디펙트 좌표가 설정된 웨이퍼를 제공하고,상기 웨이퍼 검사면에 레이저 광을 경사지게 조사하되, 상기 레이저 광은 상기 웨이퍼 검사면의 디펙트에 의해 산란되고,광원부에 연결된 얼라인 유닛을 이용하여 상기 레이저 광이 광학현미경의 시야범위에 들어가도록 상기 광원부를 회전 및 이동시키고,상기 산란된 레이저 광을 상기 광학현미경으로 감지하여 웨이퍼 디펙트를 재검출하고,상기 재검출된 디펙트의 좌표를 기준으로 상기 웨이퍼를 주사전자현미경으로 이송하고,상기 주사전자현미경으로 상기 웨이퍼 디펙트를 리뷰하는 것을 포함하는 웨이퍼 디펙트 검사방법.
