Abstract: PURPOSE:To obtain an integrated circuit having high density and high reliability by operating a tungsten layer in a first level metal as an etching stop during the etching of second layer aluminum. CONSTITUTION:An insulating layer 12 is formed onto a semiconductor substrate 10, and a metallized first level 14 coated with a surface layer 16 consisting of tungsten and composed of one or more of aluminum-strips is shaped onto the surface of the insulating layer 12 through photography. An intermetallic insulating layer 26 is deposited so as to surround the metallized first level 14, and a metallized second level 32 is connected to the metallized first level 14 through an opening in the intermetallic insulating layer.
