Abstract

PURPOSE:To improve the workability in the step of forming by an anodic oxidation method electrode wirings of aluminum metal on semiconductor or insulating film substrate by forming the electrode wirings with an insulating film such as an oxidized film or nitrided film as a mask and further employing as a cover for the electrode wiring part the insulating film. CONSTITUTION:After aluminum metal 3 is deposited on an insulating film substrate 4, a CVD oxidized film is thinly grown as an insulating film 7, the electrode wirings of a photoresist 1 is patterned, with the photoresist 1 as a mask the film 7 is dry etched, thereby performing the patterning. After the photoresist 1 is removed, an anodic oxidation is performed with aqueous solution of oxalic acid. Then, the aluminium metal 3 except the part on which the insulating film 7' exists alters to alumina 5, aluminum electrode wirings 6 are selectively formed, holes for connecting the wirings can be readily formed once, and the film 7' can be used as a wiring cover.
