Abstract

PURPOSE:To obtain high reliability of a semiconductor device by a method wherein a passivation film having an opening at the prescribed position is made to come in contact with a ball for bonding. CONSTITUTION:A bonding pad is formed as convex passivation patterns 17 are to be remained toward the central direction from the circumference of the bonding pad. In the semiconductor device constituted like this, even when Al at the part being not covered with the passivation film is corroded by water invaded from the outside, Al 33 at the parts being covered with the passivation films 18 are remained, electric connection between the ball of gold wire 15 and an inside wiring 13 is secured, and the semiconductor device having superior damp resistivity and high reliability can be obtained.
