Abstract:
1. A fin field effect transistor (Fin FET), comprising: a silicon substrate having a protrusion; active patterns on the protrusion of the silicon substrate, the active patterns including insulating layer patterns on an inside of the active patterns; an isolation layer pattern in a space between the active patterns, the isolation layer pattern including an opening exposing a sidewall of the active pattern, an upper portion of the active patterns protruding from the isolation layer pattern; a gate electrode on the protruding upper portion of the active patterns that fills the opening; impurity regions at portions of the active pattern adjacent to sidewalls of the gate electrode; an insulating interlayer covering the active pattern and the gate electrode; and at least one contact plug that passes through portions of the insulating interlayer and the active pattern adjacent to the sidewalls of the gate electrode, the at least one contact plug being in contact with the impurity regions.
