Claim Text:
1. An electrically programmable fuse for an integrated semiconductor device, comprising: a metal layer positioned above a surface of a substrate, said metal layer comprising a first electrode and a second electrode positioned at opposite end portions of said metal layer, wherein an entirety of said metal layer has a substantially planar surface that is positioned a same first distance above said surface of said substrate; a semiconductor layer positioned above said metal layer; a silicidation protection layer positioned in direct contact with and covering at least a first portion of said semiconductor layer that is positioned above and covers at least a corresponding first portion of said metal layer underlying said first portion of said semiconductor layer, wherein said silicidation protection layer is adapted to prevent silicidation of said at least said covered first portion of said semiconductor layer; and electrical connections to said first electrode and said second electrode, at least a portion of said electrical connections extending through an interlayer dielectric material positioned above said electrically programmable fuse.
