Abstract:
A semiconductor wafer to be treated is placed on a susceptor made of quartz installed in a chamber, and is heated by light irradiation from halogen lamps. Before the first semiconductor wafer of a production lot is transported into the chamber, a preheating substrate is placed on the susceptor. Then, the preheating substrate is heated by light irradiation from the halogen lamps to preheat the susceptor. The susceptor is heated to a preheating temperature higher than a stable temperature when the semiconductor wafers of the production lot are continuously treated. This enables a structure in the chamber, other than the susceptor, to be preheated to a temperature during steady treatment of the semiconductor wafer in a short time, so that it is possible to eliminate dummy running for heating the structure in the chamber by applying heating treatment to a plurality of dummy wafers.

Claim (Index 3):
The heat treatment method according to  claim 2 , wherein\n after said step (d), said preheating substrate is transported from said chamber and the first substrate of said lot is transported into said chamber to be placed on said susceptor, at the time when the temperature of said susceptor decreases to a predetermined temperature by stopping light irradiation from said continuous lighting lamps.
