Patent ID: 7138607

Claim:
A heat processing unit comprising: a processing chamber in which a substrate is contained, a heater that heats the substrate contained in the processing chamber, a gas-introducing part that introduces a process gas into the processing chamber in order to conduct a heat process to the substrate, and a controller that controls the heater and the gas-introducing part, in accordance with a process recipe including a set temperature profile defining a relationship between a passage of time and a set temperature, in order to conduct the heat process to the substrate, wherein the set temperature profile is defined in such a manner that, with respect to the substrate during the heat process, both a central-high-temperature state wherein a temperature near a central portion thereof is higher than a temperature near a peripheral portion thereof and a peripheral-high-temperature state wherein a temperature near the peripheral portion thereof is higher than a temperature near the central portion thereof can appear, and the set temperature profile is defined in such a manner that, with respect to the substrate during the heat process, an average in time of the temperature near the central portion thereof is substantially the same as an average in time of the temperature near the peripheral portion thereof.
