    摘要： A double-gate transistor having front (upper) and back gates that are aligned laterally is provided. The double-gate transistor includes a back gate thermal oxide layer below a device layer; a back gate electrode below a back gate thermal oxide layer; a front gate thermal oxide above the device layer; a front gate electrode layer above the front gate thermal oxide and vertically aligned with the back gate electrode; and a transistor body disposed above the back gate thermal oxide layer, symmetric with the first gate. The back gate electrode has a layer of oxide formed below the transistor body and on either side of a central portion of the back gate electrode, thereby positioning the back gate self-aligned with the front gate. The transistor also includes source and drain electrodes on opposite sides of said transistor body.

    摘要： A double-gate transistor has front (upper) and back gates aligned laterally by a process of forming symmetric sidewalls in proximity to the front gate and then oxidizing the back gate electrode at a temperature of at least 1000 degrees for a time sufficient to relieve stress in the structure, the oxide penetrating from the side of the transistor body to thicken the back gate oxide on the outer edges, leaving an effective thickness of gate oxide at the center, aligned with the front gate electrode. Optionally, an angled implant from the sides of an oxide enhancing species encourages relatively thicker oxide in the outer implanted areas and an oxide-retarding implant across the transistor body retards oxidation in the vertical direction, thereby permitting increase of the lateral extent of the oxidation.

    摘要： The present invention provides a method for fabricating a planar DGFET having a back gate that is aligned to a front gate. The method of the present invention achieves this alignment by creating a carrier-depleted zone in portions of the back gate. The carrier-depleted zone reduces the capacitance between the source/drain regions and the back gate thereby providing a high-performance self-aligned planar double-gate field effect transistor (DGFET). The present invention also provides a planar DGFET having a back gate that is aligned with the front gate. The front to back gate alignment is achieved by providing a carrier-depleted zone in portions of the back gate.

    摘要： A novel transistor structure and method for fabricating the same. First, a substrate, a semiconductor region, a gate dielectric region, and a gate block are provided. The semiconductor region, the gate dielectric region, and the gate block are on the substrate. The gate dielectric region is sandwiched between the semiconductor region and the gate block. The semiconductor region is electrically insulated from the gate block by the gate dielectric region. The semiconductor region and the gate dielectric region share an interface surface which is essentially perpendicular to a top surface of the substrate. The semiconductor region and the gate dielectric region do not share any interface surface that is essentially parallel to a top surface of the substrate. Next, a gate region is formed from the gate block. Then, first and second source/drain regions are formed in the semiconductor region.
