Gate with dual gate dielectric layer and method of fabricating the same
Abstract:
A gate with dual gate dielectric layer and fabrication method thereof. A semiconductor substrate is provided, on which a dielectric layer and a patterned hard mask layer with an opening are sequentially formed. A spacer is formed on a sidewall of the opening. The semiconductor substrate is ion implanted, the spacer and the exposed dielectric layer are removed, and a gate oxide layer is formed on the bottom of the opening.
