Patent ID: 7271444

Claim:
A portion of a wrap-around-gated field-effect transistor formed on a handle wafer, the portion comprising: an silicon-on-insulator (SOI) island comprising a surface periphery with a surface facing toward the handle wafer, the SOI island extending, for a length, along a major axis in a horizontal direction, the surface of the surface periphery and the handle wafer separated by a gap to have a non-contacting relationship; and a gate electrode surrounding and supporting the SOI island, the gate electrode extending in a vertical direction from the handle wafer, the gate electrode having a thickness, in the horizontal direction, less than the length of the SOI island such that a first portion of the SOI island extends on one side of the gate electrode and a second portion of the SOI island extends on another side of the gate electrode, and the gate electrode extending entirely around the surface periphery of the SOI island such that a portion of the gate electrode is disposed in the gap between the surface of the SOI island and the handle wafer.
