半导体装置及其制造方法

Semiconductor device and method of manufacturing the same
Abstract:
A method of manufacturing a semiconductor device, includes: forming a gate insulating film on a semiconductor substrate; forming a first metal film on the gate insulating film; forming a second metal film on the first metal film; and patterning a stacked film of the first and second metal films such that the stacked film is left in a gate electrode formation region and a resistive element formation region. The method further includes: removing the second metal film in the resistive element formation region with protecting a contact hole formation region. The method further includes: forming an interlayer insulating film so as to cover the stacked film; and removing the interlayer insulating film formed in the contact hole formation region to form a contact hole leading to the second metal film.
