Abstract:
A semiconductor device includes a substrate having an active pattern thereon, a gate electrode intersecting the active pattern, and a spacer on a sidewall of the gate electrode. The gate electrode includes a first metal pattern adjacent to the active pattern. The first metal pattern has a first portion parallel to the sidewall and a second portion parallel to the substrate. A top surface of the first portion has a descent in a direction from the spacer towards the second portion.
