Claim 37:
38. A field effect transistor comprising:
a substrate;
a source electrode on the substrate;
a drain electrode separated from the source electrode;
a gate electrode on the substrate between the source electrode and the drain electrode;
a plurality of channels on the substrate between the source electrode and the drain electrode, the plurality of channels including first channels spaced apart from each other in a vertical direction, each of the first channels having a hollow cross-section; and
a gate insulating layer connected to the gate electrode and the plurality of channels, the gate insulating layer insulating the gate electrode from the source electrode, the plurality of channels, and the drain electrode, wherein
the gate electrode is separated from the first channels in a distance parallel to an upper surface of the substrate by a distance corresponding to a thickness of the gate insulating layer in the distance parallel to the upper surface of the substrate, and
the gate electrode is separated from the first channels in a distance perpendicular to the upper surface of the substrate by a distance corresponding to a thickness of the gate insulating layer in the distance perpendicular to the upper surface of the substrate.
