Abstract

PURPOSE:To prevent the occurrence of purple plague phenomenon and breakdown of an insulative film on a semiconductor device having a plated projecting electode by forming a protective insulating film and a projecting electrode on a semiconductor substrate having an Al wiring and securing this to a lead frame or the like to perform wire bonding, before coating the whole surfaces with a glass film. CONSTITUTION:An insulative film 24 is formed on all the semiconductor element surface provided with an Al wiring 25 expect for the part on which a projecting electrode is to be provided. A foundation metal layer 27 for plating is provided and masked with a photoresist layer 28 which has an opening corresponding to the part on which a projecting electrode is to be provided, and a plated projecting-electrode layer 29 is formed in the opening. Then the photoresist layer 28 and the unnecessary foundation metal layer 27 for plating are removed, and a wire 31 is connecte to the plated projecting-electrode layer 29. After the whole surfaces are coated with a deposition film 35 by vaporizing passivation glass, the whole is molded with resin. Said procedure can prevent the occurrence of purple plague phenomenon and breakdown of the insulative film when the Al wiring is provided.
