Abstract:
1. A method for manufacturing a semiconductor device, comprising: forming a specific element-containing layer containing at least one element selected from the group consisting of chlorine and carbon on a substrate by supplying a source gas containing a specific element and the at least one element selected from the group consisting of chlorine and carbon to the substrate; changing the specific element-containing layer into a nitride layer containing the at least one element selected from the group consisting of chlorine and carbon, by supplying an activated gas containing nitrogen to the substrate; forming a specific element-containing layer containing the at least one element selected from the group consisting of chlorine and carbon on the nitride layer by supplying the source gas to the substrate; and changing the specific element-containing layer formed on the nitride layer and the nitride layer into an oxide layer or an oxynitride layer having a lower concentration of the at least one element selected from the group consisting of chlorine and carbon than a concentration in the specific element-containing layer on the nitride layer and the nitride layer, by supplying an activated gas containing oxygen to the substrate;
