Abstract:

Field effect transistors are provided. An active region protrudes from a substrate and a gate electrode is provided on the active region. Source/drain regions are provided at both sides of the active region under the gate electrode, respectively. A width of a lower portion of the gate electrode is greater than a width of an upper portion of the gate electrode.
