Abstract
[해결 수단] 더미 웨이퍼에 대해 할로겐 램프 등에 의한 가열 처리를 행하여 서셉터 등의 챔버내 구조물을 온도 조절하는 더미 처리를 행한다. 미리 더미 처리를 위한 더미 레시피를 작성함과 함께, 더미 처리의 횟수의 역치인 상한값 및 하한값을 설정해 둔다. 더미 처리를 개시한 후, 더미 처리의 횟수를 계수한다. 제품이 되는 반도체 웨이퍼를 수용한 캐리어가 열처리 장치에 반입된 시점에서의 더미 처리 횟수와 설정된 상한값 및 하한값의 비교 판정을 행함으로써, 더미 처리의 종료 및 제품 웨이퍼의 처리 개시의 타이밍을 조정한다.
