Abstract:
A fuse structure and method of forming the same is described, wherein the conductive body (50) of the fuse is formed from a crystalline semiconductor body (52) on an insulator (53), preferably of a silicon-on-insulator wafer, surrounded by a fill-in dielectric (54). The fill-in dielectric (54) is preferably a material that minimizes stresses on the crystalline body (52), such as an oxide. The crystalline semiconductor body (52) may be doped. The conductive body (50) may also include a conductive layer (51), such as a silicide layer, on the upper surface of the crystalline semiconductor body (52). This fuse structure may be successfully programmed over a wide range of programming voltages and time.
