Abstract
[해결 수단] 로트를 구성하는 복수의 반도체 웨이퍼를 수용한 캐리어가 열처리 장치에 반입되고 나서 각 반도체 웨이퍼에 처리 순서 및 처리 조건을 규정한 레시피를 설정한다. 다음에, 캐리어에 수용된 각 반도체 웨이퍼의 반사율을 측정한다. 설정된 레시피와 측정된 반도체 웨이퍼의 반사율에 의거하여, 플래시 가열 처리 시의 반도체 웨이퍼의 도달 예측 온도를 산정하여, 그 산정된 도달 예측 온도를 표시한다. 표시된 도달 예측 온도를 참고로 하여 처리 조건을 설정할 수 있기 때문에, 열처리 조건의 조건 설정을 용이하게 행할 수 있다.
