Patent ID: 8564089

Claim:
A semiconductor device, comprising: a transistor element comprising a gate electrode structure, said gate electrode structure being formed above a first device region and comprising a gate material stack, said gate material stack consisting of an insulating material layer and a plurality of conductive material layers positioned above said insulating material layer, wherein said material layers of said gate material stack are arranged in a gate stack layered arrangement, said insulating material layer comprising a high-k dielectric material and said plurality of material layers comprising a metal-containing electrode material and at least one non-aluminum conductive material layer, said metal-containing electrode material comprising aluminum; and an electronic fuse comprising an electronic fuse material stack formed above a second device region, said electronic fuse material stack consisting of the same material layers as are present in said gate material stack, wherein said same material layers in said electronic fuse material stack are arranged in a same layered arrangement as said gate stack layered arrangement and wherein at least said non-aluminum conductive material layer is formed on dielectric sidewalls of said electronic fuse so as to laterally confine said aluminum comprising said metal-containing electrode material of said electronic fuse.
