A polysilicon layer is formed over the dielectric layer (50) and over the first region (20) and the second region (30). The polysilicon layer can comprise 0 to 50 atomic percent of germanium. A metal layer is formed over the polysilicon layer and one of the regions and reacted with the underlying polysilicon layer to form a metal silicide or a metal germano silicide. The polysilicon and metal silicide or germano silicide regions are etched to form transistor gate regions (60) and (90) respectively. If desired a cladding layer (100) can be formed above the metal gate structures.

    摘要: Methods are presented for fabricating transistor gate structures, wherein upper and lower metal suicides are formed above a gate dielectric. In one example, the lower silicide is formed by depositing a thin first silicon-containing material over the gate dielectric, which is implanted and then reacted with a first metal by annealing to form the lower silicide. A capping layer can be formed over the first metal prior to annealing, to prevent oxidation of the metal prior to silicidation, and a barrier layer can be formed over the lower silicide to prevent reaction with subsequently formed silicon material. In another example, the lower silicide is a multilayer silicide structure including a plurality of metal silicide sublayers.
