Abstract

A semiconductor device includes active regions extending in a first direction on a substrate; a gate electrode intersecting the active regions on the substrate, extending in a second direction, and including a contact region protruding upwardly; and an interconnection line on the gate electrode and connected to the contact region, wherein the contact region includes a lower region having a first width in the second direction and an upper region located on the lower region and having a second width smaller than the first width in the second direction, and wherein at least one side surface of the contact region in the second direction has a point at which an inclination or a curvature is changed between the lower region and the upper region.
