Semiconductor device including self-aligned contact and method of manufacturing the semiconductor device

Abstract

A semiconductor device according to some embodiments of the disclosure may include a fin type active pattern extending in a first direction, a plurality of gate structures on the fin type active pattern and extending in a second direction different from the first direction, a plurality of inter-contact insulation patterns on respective ones of the plurality of gate structures, a plurality of interlayer insulation layers on side surfaces of the plurality of gate structures, and a plurality of contact plugs respectively between pairs of the plurality of gate structures. The fin type active pattern may include a plurality of source/drains. Lower ends of the plurality of contact plugs may contact the plurality of source/drains. The plurality of gate structures may each include a first gate metal, a second gate metal, a gate capping layer, a gate insulation layer, a first spacer, and a second spacer.
