The susceptor is preheated up to a stable temperature by the heated body in which the temperature has been increased. When the semiconductor wafer as an initial processing target is carried in the chamber, the lower chamber window and the susceptor are heated up to the stable temperature. Therefore, a temperature history in all of the semiconductor wafer constructing a lot can be uniformed. Thus, a dummy run before carrying-in the semiconductor wafer as the initial processing target can be omitted.SELECTED DRAWING: Figure 8
