Abstract:
A method for manufacturing a semiconductor device, comprising:forming a dielectric film on a substrate; etching the dielectric film to form at least two of three groups of openings such that on a bottom surface of each of the first group of openings having silicon as a major constituent element, on a bottom surface of each of the second group of openings having a first metal silicide as a major constituent element, and on a bottom surface of each of the third group of openings having a first metal as a major constituent element; and forming, depending on at least two of three groups of openings formed by said etching step, at least two of three layers such that a layer having a second metal silicide as a major constituent element on the bottom of each of the first group of openings, a layer having the second metal silicide as a major constituent element on the bottom of each of the second group of openings, and a layer having a second metal as a major constituent element on the bottom of each of the third group of openings, simultaneously, by one single chemical vapor deposition process.
