Claims (6)
- 웨이퍼상의 스캔영역을 라인스캐닝하여 이로부터 이미지를 얻는 단계; 및 상기 얻어진 이미지를 판독하여 에지영역내에 결함이 존재하는지 여부를 판단하는 단계를 포함하는 웨이퍼의 결함 탐지방법.
- 제 1항에 있어서, 상기 이미지의 판독과정은 당해 얻어진 이미지로부터 에지영역의 패턴을 추출하고, 추출된 에지영역의 폭을 측정하여 기준값과 비교판단함으로써 수행되어지는 웨이퍼의 결함 탐지방법.
- 제 1항에 있어서, 라인스캐닝은 적어도 1회전 이상의 원주에 대하여 웨이퍼를 회전시켜 수행되는 웨이퍼의 결함 탐지방법.
- 제 1항에 있어서, 라인스캐닝은 웨이퍼의 양면에 대하여 수행되는 웨이퍼의 결함 탐지방법.
- 웨이퍼 표면에 광을 조사하기 위한 광원; 스캔영역을 가지며, 웨이퍼가 놓여지는 스테이지; 상기 웨이퍼를 상기 스테이지상에 회전시키는 회전부재; 상기 스테이지의 상기 스캔영역에 광을 조사하여 상기 웨이퍼를 라인단위로 촬상하는 촬영부; 상기 촬영부로부터 입력되는 영상정보를 이용하여 웨이퍼의 결함유무를 검사하 는 영상처리부; 및 영상처리된 결과를 표시해주는 디스플레이부를 포함하는 웨이퍼의 결함 탐지장치.
- 제 5항에 있어서, 상기 촬영부는 웨이퍼의 해당 촬영부위의 상부 및 하부에 각각 구비되어지는 웨이퍼의 결함 탐지장치.
