METHOD OF MANUFACTURING SEMICONDUCTOR DEVICE, METHOD OF PROCESSING SUBSTRATE, SUBSTRATE PROCESSING APPARATUS, AND PROGRAM

摘要

A method of manufacturing a semiconductor device is provided, which enables the film quality to be improved when the film is formed on a substrate at a low temperature, thus forming fine patterns. The method of manufacturing a semiconductor device includes: forming the film on a substrate by alternately supplying at least a source gas and a reactive gas to the substrate while maintaining the substrate at a first temperature by heating; and modifying the film by supplying a modification gas excited by plasma to the substrate with the film formed thereon while naturally cooling the substrate with the film formed thereon to a second temperature without heating the substrate, the second temperature being lower than the first temperature.
