A semiconductor integrated circuit device including a substrate with a first element region of a P type and a second element region of an N type, a channel active region that extends in the first element region or the second element region, the channel active region including a plurality of channels, a plurality of gate lines that extend in a second direction intersecting and include a gate metal layer, and a gate insulating film in contact with the gate metal layer, a plurality of first spacers on opposite side portions of respective ones of the gate lines, and a plurality of source/drain regions that are between ones of the plurality of gate lines. The channel active region includes a first channel directly on the substrate, and a second channel spaced apart from the first channel and extends into the gate metal layer.

Semiconductor integrated circuit device and manufacturing method thereof

Semiconductor devices and methods of fabricating the same are provided. The method includes forming on a substrate an active pattern that protrudes from the substrate and extends in one direction; forming on the active pattern a sacrificial gate structure that extends in a direction intersecting the active pattern; forming on a side surface of the sacrificial gate structure a first spacer including a first portion at a lower level than a top surface of the active pattern and a second portion on the first portion, and reducing a thickness of the second portion of the first spacer.
