A method produces a transistor with an overlapping gate. A first gate region is placed on a substrate between two source/drain regions. The first gate region includes a polysilicon region on top of a dielectric region. Gate overlap regions are placed around the polysilicon region. The gate overlap regions extend out over the two source/drain regions. The gate overlap regions are formed of a metal-silicide layer, for example Titanium-silicide. A top portion of the metal-silicide layer is oxidized to form a silicon dioxide layer on top of the metal-silicide layer. At the time of oxidation, the metal-silicide layer is also annealed to which further helps to improves the Titanium-silicide stoichiometry.
