A semiconductor device includes a first gate pattern and a second gate pattern on a substrate, the first gate pattern and the second gate pattern being spaced apart from each other, and a separation pattern that separates the first gate pattern and the second gate pattern from each other. The first gate pattern includes a first high-k dielectric pattern and a first metal-containing pattern on the first high-k dielectric pattern, the first metal-containing pattern covering a sidewall of the first high-k dielectric pattern. The second gate pattern includes a second high-k dielectric pattern and a second metal-containing pattern on the second high-k dielectric pattern, and the separation pattern is in direct contact with the first metal-containing pattern and spaced apart from the first high-k dielectric pattern.

Semiconductor device including fin field effect transistor with separation layer

A semiconductor device is provided. The semiconductor device includes: a substrate with an active region extending in a first direction; an element isolation layer, adjacent to the active region, in the substrate; a gate electrode on the substrate and extending in a second direction which crosses the first direction; a plurality of channel layers on the active region, spaced apart from each other along a third direction perpendicular to an upper surface of the substrate, and surrounded by the gate electrode; and a source/drain region provided in a recess of the active region adjacent to the gate electrode, and connected to the plurality of channel layers. In the first direction, the gate electrode has a first length on the active region and a second length, greater than the first length, on the element isolation layer.
