Patent ID: 7807553

Claim:
A semiconductor fabrication method having a substrate heating step of heating, using a substrate heating apparatus having a heater to heat a substrate placed in a process chamber, a suscepter installed between the heater and the substrate, and on which the substrate is mounted; and a heat receiving member installed to cover the substrate from above the suscepter, and receives heat from the heater via the suscepter, wherein the heat receiving member is installed to be placed on the suscepter, a ventilating portion is formed as a through-hole in a circumferential wall of the heat receiving member to create a space between the heat receiving member and the substrate to communicate with a space in the process chamber, a substrate placed in the process chamber adapted to be evacuated, the substrate heating step comprising steps of: placing a substrate on the suscepter incorporating the heater; covering the substrate from above the suscepter by the heat receiving member having the ventilating portion; evacuating the process chamber; and heating the substrate by the heater after an interior of the process chamber has reached a predetermined vacuum degree, wherein in the step of evacuating the process chamber, a gas produced in the space formed between the heat receiving member and the substrate is evacuated through the ventilating portion.
