A method of forming a semiconductor device includes implanting a precipitate into a gate conductor of an at least partially formed semiconductor device. The gate conductor including a plurality of semiconductor grains. The boundaries of adjacent grains forming a dopant migration path. A plurality of precipitate regions are formed within the gate conductor. At least some of the precipitate regions located at a junction of at least two grains. The gate conductor of the at least partially formed semiconductor device is doped with a dopant. The dopant diffuses inwardly along the dopant migration path.
