Abstract

A semiconductor device comprising a gate electrode on a substrate, a source/drain pattern on the substrate on a side of the gate electrode, and a gate contact plug on the gate electrode are disclosed. The gate contact plug may include a first gate contact segment, and a second gate contact segment that extends in a vertical direction from a top surface of the first gate contact segment. An upper width of the first gate contact segment may be greater than a lower width of the second gate contact segment.
