ABSTRACT:
A heat processing method for a semiconductor process includes placing a plurality of target substrates stacked at intervals in a vertical direction within a process field of a process container. Each of the target substrates includes a process object layer on its surface. Then, the method includes supplying an oxidizing gas and a deoxidizing gas to the process field while heating the process field, thereby causing the oxidizing gas and the deoxidizing gas to react with each other to generate oxygen radicals and hydroxyl group radicals, and performing oxidation on the process object layer of the target substrates by use of the oxygen radicals and the hydroxyl group radicals. Then, the method includes heating the process object layer processed by the oxidation, within an atmosphere of an annealing gas containing ozone or oxidizing radicals, thereby performing annealing on the process object layer.
