A method of fabricating a semiconductor device which prevents a pitting phenomenon from occurring on a gate insulating layer is provided. The method of fabricating of a semiconductor device according to the present invention comprises: depositing a first gate material including at least a gate insulating layer and a first metal layer in a first region on a semiconductor substrate; depositing a second gate material layer including at least a gate insulating layer and a polysilicon layer in a second region on the semiconductor substrate; forming a hard mask pattern on the first gate material layer and on the second gate material layer; and forming a first gate pattern and a second gate pattern by etching the first gate material layer and the second gate material layer, using the hard mask pattern as a mask, wherein the step of forming the first gate pattern and the second gate pattern comprises dry etching the first metal layer and the polysilicon layer simultaneously using a first etching gas composition including both CF4 and CH4, such that when the first metal layer is completely etched, a polysilicon layer of at least a predetermined minimum protective thickness remains covering the underlying gate insulating layer. The etch rate of the first metal layer to the etch rate of polysilicon can be relatively increased by the method of this invention, and, as a result, a gate pattern with high density can be effectively formed.
