Abstract

A semiconductor device includes an interlayer insulating film formed on a substrate, the insulating layer including a trench. A gate insulating layer is formed on a bottom surface of the trench and a reaction prevention layer is formed on the gate insulating layer on the bottom surface of the trench. A replacement metal gate structure is formed on the reaction prevention layer of the trench to fill the trench.
