METHOD OF MANUFACTURING SEMICONDUCTOR DEVICE, METHOD OF PROCESSING SUBSTRATE, SUBSTRATE PROCESSING APPARATUS, AND RECORDING MEDIUM
Abstract: there is provided a technique that includes: (a) forming a base film, which has a reactivity with a film-forming inhibitor higher than a reactivity between the film-forming inhibitor and an inner surface of a concave portion formed on a surface of a substrate, at least in an upper portion in the concave portion by supplying a pre-treatment gas to the substrate; (b) forming a film-forming inhibition layer on a portion of a surface of the base film, which is formed in the upper portion in the concave portion, by supplying the film-forming inhibitor to the substrate; and (c) growing a film starting from a portion in the concave portion where the film-forming inhibition layer is not formed, by supplying a film-forming gas to the substrate.
