Abstract

Example embodiments herein relate to a method of fabricating a semiconductor device. The method may include forming a liner insulating layer on a surface of a gate pattern to have a first thickness. Subsequently, a gap fill layer may be formed on the liner insulating layer by flowable chemical vapor deposition (FCVD) or spin-on-glass (SOG). The liner insulating layer and the gap fill layer may be recessed such that the liner insulating layer has a second thickness, which is smaller than the first thickness, in the region in which a metal silicide will be formed. Metal silicide may be formed on the plurality of gate patterns to have a relatively uniform thickness using the difference in thickness of the liner insulating layer.
