Abstract:
A barrier layer BAL is formed so as to be in contact with an aluminum pad ALP. A titanium alloy layer including a titanium film and a titanium nitride film is formed as barrier layer BAL. A seed layer SED is formed so as to be in contact with barrier layer BAL. A copper film is formed as seed layer SED. A silver bump AGBP is formed so as to be in contact with seed layer SED. Silver bump AGBP is constructed with a silver film AGPL formed by an electrolytic plating method. A tin alloy ball SNB is bonded to silver bump AGBP.

Claim (Index 1):
A semiconductor device comprising:\n an element formation region defined in a semiconductor substrate; a semiconductor element formed in the element formation region; a multilayer interconnect structure formed so as to cover the semiconductor element, the multilayer interconnect structure including a plurality of interconnect layers and an interlayer dielectric electrically insulating the plurality of interconnect layers from each other; a pad electrode electrically connected to one of the plurality of interconnect layers; a barrier layer formed so as to be in contact with the pad electrode; a silver bump electrically connected to the pad electrode with the barrier layer interposed therebetween; and a solder bump formed so as to be in contact with the silver bump.
