摘要: A method of manufacturing a semiconductor device, where on top of a substrate having already-completed circuit elements and wiring, etc., an insulation underlayer a, Pt layer for a bottom electrode, a dielectric film and a Pt layer for a top electrode are shaped.A top electrode, capacitance insulation film and bottom electrode are formed by etching the Pt layer for the top electrode or the Pt layer for the bottom electrode using an etching gas contained an S component while composing a Pt and S compound. Alternatively the Pt and S compound can be composed first, and then the compound can be etched.
