ABSTRACT:
A semiconductor device in accordance with the present invention has a passivation film. The passivation film is provided on the entire surface of a substrate provided with a bonding pad and a scribe line. After applying a photoresist on the entire surface of the passivation film, a photoresist pattern is contoured. The photoresist pattern thus contoured is exposed and developed so as to be patterned. The photoresist is patterned so as to (1) provide an opening which is a connected region of a region to be the bonding pad and a region to be the scribe line, and (2) make angles of the patterning obtuse angles. Then, the passivation film is etched, and the photoresist is removed. With this arrangement, a removing solution and a resist residue do not remain in the opening section provided on a portion of the passivation film corresponding to the bonding pad, thereby preventing a quality deterioration such as corrosion of the bonding pad and breakage of wire bonding.
