    摘要: A trigate device having an extended metal gate electrode comprises a semiconductor body having a top surface and opposing sidewalls formed on a substrate, an isolation layer formed on the substrate and around the semiconductor body, wherein a portion of the semiconductor body remains exposed above the isolation layer, and a gate stack formed on the top surface and opposing sidewalls of the semiconductor body, wherein the gate stack extends a depth into the isolation layer, thereby causing a bottom surface of the gate stack to be below a top surface of the isolation layer.
