Abstract:
A process for manufacturing a semiconductor integrated circuit device, comprising the steps of:(a) forming a first film, which has a layer made of a metal or conductive metal oxide selected from the group consisting of Pt, Ir, IrO.sub.2, Rh, RhO.sub.2, Os, OsO.sub.2, Ru, RuO.sub.2, Re, ReO.sub.3, Pd and Au, overlying a first major surface of a wafer;(b) forming a photoresist of a first pattern overlying said first film, the photoresist of a first pattern having, in vertical cross section, a lower side face, an upper side face and an upper surface, the upper side face forming an edge portion with the upper surface, the lower side face being substantially vertical, and the upper side face being either (1) upwardly tapered or (2) rounded at the edge portion; and(c) after said forming the photoresist of the first pattern, patterning said first film by dry-etching, so as to form a first film pattern, by using said photoresist of the first pattern as a mask.
