A method of setting a work function of a filly silicided semiconductor device, and related device. At least some of the illustrative embodiments are methods comprising forming a gate stack over a semiconductor substrate (the gate stack comprising a dielectric layer, a suicide layer on the dielectric layer that defines a metal-dielectric layer interface, and a polysilicon layer on the suicide layer), depositing a metal layer over the gate stack, annealing to induce a reaction between the polysilicon layer and the metal layer, and delivering a work function-setting dopant to the metal-dielectric layer interface by way of the reaction. |
