Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device comprising:
a substrate;
an active pattern extending in a first horizontal direction on the substrate;
a gate electrode extending in a second horizontal direction different from the first horizontal direction on the active pattern;
a source/drain region on at least one side of the gate electrode;
a source/drain contact extending into the source/drain region and including a filling layer and a barrier layer along a sidewall of the filling layer; and
a silicide layer between the source/drain region and the filling layer, the silicide layer including a first sidewall in contact with the filling layer and a second sidewall in contact with the source/drain region,
wherein the barrier layer is not between the filling layer and the source/drain region, and
wherein the filling layer is formed as a single film, and the filling layer is in contact with the barrier layer.
