    摘要: One embodiment of a method for forming a semiconductor device can include forming a gate pattern on a semiconductor substrate and performing a selective re-oxidation process on the gate pattern in gas ambient including hydrogen, oxygen, and nitrogen. When the gate pattern includes a tunnel insulation layer, a metal nitride layer and a metal layer, the selective re-oxidation process heals the etching damage of a gate pattern and simultaneously prevents oxidation of the metal nitride layer and a tungsten electrode.
