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 18):
A method of manufacturing a semiconductor device, the method comprising:\n forming gate structures on a substrate; forming a preliminary interlayer insulation pattern to fill a gap between the gate structures; forming a mask pattern on the gate structures and the preliminary interlayer insulation pattern to cover a contact-forming region; partially etching an upper portion of the preliminary interlayer insulation pattern using the mask pattern as an etching mask to form a recess and an interlayer insulation patter under the recess; forming a capping pattern on the interlayer insulation pattern to fill the recess; implanting an ion on the gate structures, the interlayer insulation pattern, and the capping pattern; and etching the interlayer insulation pattern doped with an ion to form a contact hole.
