摘要:
A method of fabricating a contact plug of a semiconductor device is provided, the method includes forming a gate pattern on a substrate, forming a capping pattern to cover an upper surface and sidewalls of the gate pattern, forming an interlayer insulation layer on the substrate such that the interlayer insulation layer exposes an upper surface of the capping pattern, and removing a portion of the capping pattern and the interlayer insulation layer such that the upper surface of the capping pattern is planarized.
