Abstract:
1. A semiconductor device comprising: a semiconductor substrate provided with a desirable element region; an electrode pad formed to come in contact with a surface of the semiconductor substrate or a wiring layer provided on the surface of the semiconductor substrate; a bonding pad formed on a surface of the electrode pad through an intermediate layer; a bump formed on the bonding pad, and a resin insulating film formed on a peripheral edge of the bonding pad and the bump, wherein said resin insulating film covers an interface of the bonding pad and a part of the bump being exposed to a side surface thereof, wherein a width of the bonding pad is equal to a width of the bump, and wherein, in a vicinity of the peripheral edge of the bonding pad, a nitride film is formed between the electrode pad and the bonding pad, and the nitride film includes a convex portion, and the bonding pad is formed on an upper face and side faces of the convex portion of the nitride film.
