Abstract:
A method of manufacturing a semiconductor device, the method including forming dummy gate structures on a substrate; forming spacers on sidewalls of the dummy gate structures; forming a preliminary first interlayer insulation pattern to fill a gap between adjacent spacers; etching an upper portion of the preliminary first interlayer insulation pattern through a first etching process to form a preliminary second interlayer insulation pattern; implanting an ion on the dummy gate structures, the spacers, and the preliminary second interlayer insulation pattern through an ion-implanting process; etching an upper portion of the preliminary second interlayer insulation pattern through a second etching process to form an interlayer insulation pattern having a flat upper surface; and forming a capping pattern on the interlayer insulation pattern to fill a gap between the spacers.

Claim (Index 16):
The method as claimed in  claim 15 , wherein an etching selectivity between silicon oxide and silicon nitride in the second etching process is smaller than an etching selectivity between silicon oxide and silicon nitride in the first etching process.
