Semiconductor devices are provided. The semiconductor devices may include a first wire pattern extending in a first direction on a substrate and a second wire pattern on the first wire pattern. The second wire pattern may be spaced apart from the first wire pattern and extends in the first direction. The semiconductor devices may also include a first gate structure at least partially surrounding the first wire pattern and the second wire pattern, a second gate structure spaced apart from the first gate structure in the first direction, a first source/drain region between the first gate structure and the second gate structure, a first spacer between a bottom surface of the first source/drain region and the substrate, a first source/drain contact on the first source/drain region, and a second spacer between the first source/drain contact and the first gate structure.

Semiconductor devices

A semiconductor device includes a substrate, a gate electrode on the substrate, a gate spacer on a sidewall of the gate electrode, an active pattern penetrating the gate electrode and the gate spacer, and an epitaxial pattern contacting the active pattern and the gate spacer. The gate electrode extends in a first direction. The gate spacer includes a semiconductor material layer. The active pattern extends in a second direction crossing the first direction.

Semiconductor device including non-sacrificial gate spacers and method of fabricating the same

A semiconductor device including a fin field effect transistor (fin-FET) includes active fins disposed on a substrate, isolation layers on both sides of the active fins, a gate structure formed to cross the active fins and the isolation layers, source/drain regions on the active fins on sidewalls of the gate structure, a first interlayer insulating layer on the isolation layers in contact with portions of the sidewalls of the gate structure and portions of surfaces of the source/drain regions, an etch stop layer configured to overlap the first interlayer insulating layer, the sidewalls of the gate structure, and the source/drain regions, and contact plugs formed to pass through the etch stop layer to contact the source/drain regions. The source/drain regions have main growth portions in contact with upper surfaces of the active fins.

Semiconductor device including fin-FET and misaligned source and drain contacts

A semiconductor device including a buried insulating layer on a substrate; a lower semiconductor layer on the buried insulating layer, the lower semiconductor layer including a first material; a channel pattern on the lower semiconductor layer, the channel pattern being spaced apart from the lower semiconductor layer and including a second material different from the first material; and a gate electrode surrounding at least a portion of the channel pattern.
