Abstract
PURPOSE:To improve the resolution of a resist layer for assuring a fine pattern metal wiring layer by covering an electrode wiring layer with an insulating film having a greater ratio of etching selection, and removing the resist layer by etching with use of both the resist layer and insulating film as a mask. CONSTITUTION:There are laminated in succession a metal wiring layer 3 with aluminum deposited by sputtering on an oxide film 2 covering a semiconductor substrate 1 surface therewith, an insulating film 4 having a greater ratio of etching selection to aluminum covering the metal wiring layer 3 therewith, and a patterned resist layer 5 deposited on the insulating film 4. Then, the insulating film 4 is dry-etched with use of the resist layer 5 as a mask. Moreover, the metal wiring layer 3 is etched with use of the resist layer 5 and the insulating film 4 as a mask. Thus, resolution of the resist layer is improved, thereby assuring a fine pattern metal wiring layer followed by a simplified removal process of the resist layer.
