Original Abstract Submitted
A semiconductor device includes: a substrate; an active region extending in a first direction on the substrate; a gate structure extending in a second direction on the active region and intersecting the active region; a source/drain region on the active region on a side of the gate structure; a separation pattern extending in the first direction and separating the gate structure; and a contact structure on the separation pattern and crossing the separation pattern, the contact structure being electrically connected to the source/drain region, wherein the contact structure includes a first portion and a second portion, the first portion contacts the separation pattern, the second portion contacts the source/drain region, a lower surface of the second portion is at a level lower than a lower surface of the first portion, and a lowermost end of the contact structure is spaced apart from the separation pattern.
