    Abstract: A double patterning method of forming a plurality of hole patterns having a small pitch using etch selectivities includes forming a patterning mask pattern defining a preliminary hole exposing an upper surface of a buffer mask layer, an inner spacer exposing the upper surface of the buffer mask layer on an inner wall of the preliminary hole, a buffer mask pattern having a first hole, and a core insulating pattern filling the preliminary hole and the first hole, an outer spacer to expose a first portion of the patterning mask pattern on the exposed portion of the outer side of the inner spacer, and an empty space exposing a first portion of the buffer mask pattern. A second portion of the patterning mask pattern and a second portion of the buffer mask pattern are exposed. A second hole is formed by removing the second portion of the buffer mask pattern.

    Abstract: Disclosed is a method of manufacturing semiconductor devices. A dummy gate structure is formed on a pattern area defined by an edge area of a substrate. An interlayer insulating layer pattern is formed to cover the pattern area and exposing the edge area of the substrate. A blocking pattern is formed on the interlayer insulating layer pattern such that the edge area of the substrate is covered with the blocking pattern and the pattern area of the substrate is exposed through the blocking pattern. A gate hole in the pattern area of the substrate in correspondence to the dummy gate structure, and a metal gate structure is formed in the gate hole. Accordingly, the edge area of the substrate is protected in the etching process and the deposition process of the replacement gate metal (RGM) process.
