Abstract:
1. A semiconductor device, comprising: a transistor element positioned in and above an active region of a semiconducting substrate, said transistor element comprising a gate electrode structure, said gate electrode structure comprising a gate dielectric layer positioned above said active region and a metal-containing electrode material positioned above said gate dielectric layer, wherein said gate dielectric layer comprises a first high-k dielectric material; and a fuse body positioned above an isolation region of said semiconducting substrate, said fuse body comprising a layer of dielectric material positioned above said isolation region, a first metal-containing cap layer positioned above said layer of dielectric material, and a semiconductor material positioned above said first metal-containing cap layer, wherein said semiconductor material has an upper portion and a lower portion, said upper portion comprising an electrically inert species and having an increased etch resistivity compared to said lower portion.
