Claims (6)
- 여러개의 요입문자가 적어도 일렬로 새겨져 형성된 패턴을 가지는 피측정영역(7)을 한쪽면에 구비한 피측정 부재와 ; 화상읽기 장치와의 조합에 있어서 ; 상기 화상 읽기 장치는, 피측정영역의 크기에 상당하는 크기의 조사스포트를 가지는 비응집적인 평행광선을 패턴상에 동시에 조사하기 위한 조사수단과 ; 피측정영역(7)으로부터의 정반사광에서 벗어난 반사광을 수광하도록 정반사광축(b)에서 이동하여 위치하는 수광면을 가지며, 상기 수광한 빛으로부터 상기 측정부재 상의 패턴을 측정하는 측정수단 ; 및 상기 피측정부재와 상기 조사수단의 사이에 형성되고, 평행광선의 주변광이 상기 피측정영역(7)으로 입사되는 것을 저지하는 저지수단을 포함하여 구성되며, 상기 측정수단의 상기 수광면은 상기 패턴으로부터의 정반사광축(b)에 대하여 2도 내지 5도의 각도를 가지는 화상 읽기 장치.
- 제 1항에 있어서, 상기 조사수단을 측정광이 패턴에 대하여 60도 내지 80도의 입사각도를 가지도록 피측정부재에 대하여 형성되어 있는 화상 읽기 장치.
- 제 1항에 있어서, 패턴의 측정중에 상기 피측정부재의 이동을 방지하기 위하여 피측정부재를 고정하는 수단을 더욱 포함하여 구성되는 화상 읽기 장치.
- 제 1항에 있어서, 상기 저지수단은 상기 측정수단의 상기 수광면에 의한 정반사광축(b)으로부터 어긋난 방향으로 측정광의 주변광이 피측정부재로 입사되는 것을 방지하기 위한 차광부재를 가지는 화상 읽기 장치.
- 제 1항에 있어서, 상기 요입문자는 0.2 내지 0.8 미크론의 깊이를 가지는 화상 읽기 장치.
- 제 5항에 있어서, 상기 피측정부재는 오리엔테이션 플래트면을 가지는 반도체 웨이퍼(6)이며 상기 다수개의 요입문자는 상기 반도체 웨이퍼(6)의 품질을 전체적으로 표시하는 마크를 구성하도록 오리엔테이션 플래트면을 따라 배열되는 화상 읽기 장치.
