Patent ID: 8564131

Claim:
A semiconductor device, comprising: a first interconnect layer disposed over a substrate where a functional semiconductor device is formed; an inter layer dielectric directly covering a portion of top surface and side surfaces of said first interconnect layer; a silicon nitride film formed so as to cover entirely a top surface of said inter layer dielectric; a metal interconnect layer covering said silicon nitride film, said metal interconnect layer being consisted of gold material and serving as a bonding pad; a passivation film which is formed directly on a surface of the silicon nitride film, directly and entirely surrounding the metal interconnect layer including a surface and a side wall thereof, and a barrier layer disposed between the metal interconnect layer and the first interconnect layer including on inner surface of a through hole that is formed on the silicon nitride film, and thickness of the barrier layer being equivalent at least on the inner surface of the through hole, wherein a portion of the passivation film is removed at a part of a region of the surface of the metal interconnect layer, thereby the part of the region of the surface of the metal interconnect layer is exposed from the passivation film, and a bonding wire is connected to the exposed part of the region of the surface of the metal interconnect layer, wherein a projection area of said region connected with the bonding wire is overlapped with said functional semiconductor device, and wherein the inter layer dielectric includes a first inter layer dielectric formed on the first interconnect layer and a second inter layer dielectric formed on a periphery of the first interconnect layer, and the first inter layer dielectric is thinner than the second inter layer dielectric.
