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 source gas containing a specific element and the at least one element selected from the group consisting of chlorine and carbon to the substrate in a processing container; 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 activated gas containing nitrogen to the substrate in the processing container; and changing 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 the concentration in the nitride layer, by supplying activated gas containing oxygen to the substrate in the processing container, wherein this cycle is set as one cycle and this cycle is repeated for multiple number of times, to form an oxide film or an oxynitride film of a prescribed thickness on the substrate.
