Manufacturing method of semiconductor substrate and substrate processing apparatus

摘要

A first processing gas containing a first element and a second processing gas containing a second element are alternately supplied to a surface of a substrate placed in a processing chamber, to thereby form a first thin film, and a second processing gas and a third processing containing the first element and different from the first processing gas are alternately supplied, to thereby form a second thin film on the first thin film, having the same element component as that of the first thin film.
