Patent ID: 7312535

Claim:
A semiconductor device, comprising: an interconnect layer provided on a semiconductor substrate; a protective film provided on said interconnect layer; an electrode pad provided on said protective film; and an anti-oxidizing layer containing a same element as an element in said interconnect layer that is chemically bonded or alloyed with a different element which is different from said element contained in said interconnect layer, said anti-oxidizing layer being disposed between said interconnect layer and said protective film, wherein said electrode pad is in electrical contact with said interconnect layer and is disposed on said protective film in a position to permit contact by a probe, and wherein said different element of said anti-oxidizing layer is a metal having a lower oxidation-reduction potential than that of said element contained in said interconnect layer, said element being a metal, and said anti-oxidizing layer being disposed between said interconnect layer and said protective film in a position that inhibits corrosion of said interconnect layer when an interface between said electrode pad and said interconnect layer is damaged by said probe, and wherein said different element is a group IV element or a group VI element in long form periodic table.
