摘要： A field effect transistor gate structure and a method of fabricating the gate structure with a high-k gate dielectric material and high-k spacer are described. A gate pattern or trench is first etched in a dummy organic or inorganic film deposited over a silicon substrate with source/drain regions. A high-k dielectric material liner is then deposited on all exposed surfaces. Excess poly-silicon gate conductor film is then deposited within and over the trench to provide adequate overburden. Poly-silicon is then planarized with chemical mechanical polishing or etch-back methods such that the high-k material film on top of the dummy film surface is removed during this step. In the final step, the dummy film is disposed off, leaving the final transistor gate structure with high-k gate dielectric and high-k spacer surrounding the gate conductor poly-silicon, with the entire gate structure fabricated to form an FET device on a silicon substrate.

摘要： A plasma etch method for etching a dielectric layer and an etch stop layer to reach a metal silicide layer formed thereunder employs for etching the etch stop layer an etchant gas composition comprising a fluorine containing gas and a nitrogen containing gas, preferably with a carrier gas such as argon or helium, but without an oxygen containing gas or a carbon and oxygen containing gas. The plasma etch method is selective for the etch stop layer with respect to the metal silicide layer, thus maintaining the physical and electrical integrity of the metal silicide layer.
