    摘要: Semiconductor devices and fabrication methods are presented, in which transistor gate structures are created using doped metal silicide materials. Upper and lower metal silicides are formed above a gate dielectric, wherein the lower metal silicide is doped with n-type impurities for NMOS gates and with p-type impurities for PMOS gates, and wherein a silicon may, but need not be formed between the upper and lower metal silicides. The lower metal silicide can be deposited directly, or may be formed through reaction of deposited metal and poly-silicon, and the lower silicide can be doped by diffusion or implantation, before or after gate patterning.

    摘要: Fabricating a semiconductor includes depositing a metal layer outwardly from a dielectric layer and forming a mask layer outwardly from a first portion of the metal layer. Atoms are incorporated into an exposed second portion of the metal layer to form a composition-altered portion of the metal layer. The mask layer is removed from the first portion of the metal layer and a barrier layer is deposited outwardly from the metal layer. A poly-Si layer is deposited outwardly from the barrier layer to form a semiconductor layer, where the barrier layer substantially prevents reaction of the metal layer with the poly-Si layer. The semiconductor layer is etched to form gate stacks, where each gate stack operates according to one of a plurality of work functions.
