METHOD OF MANUFACTURING SEMICONDUCTOR DEVICE, SUBSTRATE PROCESSING APPARATUS, AND RECORDING MEDIUM

摘要

The present disclosure suppresses oxidation of a base film on a substrate surface during the formation of an oxide film. A method of manufacturing a semiconductor device according to the present disclosure includes forming an initial layer including a predetermined element and having a thickness of several atomic layers on a substrate in a process chamber by supplying a predetermined-element-containing gas to the substrate, and forming an oxide film including the predetermined element on the initial layer by performing a cycle a predetermined number of times, the cycle including supplying a precursor gas including the predetermined element to the substrate in the process chamber and supplying an oxygen-containing gas and a hydrogen-containing gas to the substrate heated in the process chamber under a pressure lower than an atmospheric pressure.
