Abstract:
Provided are field effect transistors and methods of fabricating the same. The transistor may include a substrate with an active pattern, the active pattern having a top surface and two sidewalls, a gate electrode proximal to the top surface and the sidewalls of the active pattern and crossing the active pattern, a gate spacer covering a sidewall of the gate electrode, a gate dielectric pattern at a bottom surface of the gate electrode, a source electrode on the active pattern at one side of the gate electrode, a drain electrode on the active pattern at another side of the gate electrode, and silicide patterns on surfaces of the source and drain electrodes, respectively. The gate dielectric pattern includes at least one high-k layer and the gate spacer has a dielectric constant that is smaller than that of the gate dielectric pattern.

Claim (Index 1):
A field effect transistor, comprising:\n a substrate including an active fin; a gate insulating layer covering the active fin, the gate insulating layer formed of at least one high-k dielectric material; a gate pattern on the gate insulating layer to cross the active fin; gate spacers at sidewalls of the gate pattern to cross the active fin; a source electrode on the active fin at one side of the gate pattern; a drain electrode on the active fin at another side of the gate pattern; and silicide patterns on the source and drain electrodes, respectively, wherein the gate pattern comprises a first gate electrode and a second gate electrode on the first gate electrode, the first gate electrode extending from a region between the second gate electrode and the gate insulating layer to a region between a sidewall of the second gate electrode and the gate spacers, and wherein the first gate electrode directly contacts inner sidewalls of the gate spacers and a top surface of the gate insulating layer.
