    摘要: A semiconductor fin suspended above a top surface of a semiconductor layer and supported by a gate structure is formed. An insulator layer is formed between the top surface of the semiconductor layer and the gate structure. A gate spacer is formed, and physically exposed portions of the semiconductor fin are removed by an anisotropic etch. Subsequently, physically exposed portions of the insulator layer can be etched with a taper. Alternately, a disposable spacer can be formed prior to an anisotropic etch of the insulator layer. The lateral distance between two openings in the dielectric layer across the gate structure is greater than the lateral distance between outer sidewalls of the gate spacers. Selective deposition of a semiconductor material can be performed to form raised active regions.

    摘要: Methods form complementary metal oxide semiconductor (CMOS) devices that include a first transistor and a complementary second transistor, and an output connected to the first transistor and the second transistor. The first transistor includes a first channel region, a first back gate, a first delay element between the output and the first back gate, and a first back gate insulator separating the first back gate from the first channel region. The second transistor includes a second channel region, a second back gate, a second delay element between the output and the second back gate, and a second back gate insulator separating the second back gate from the second channel region. The first delay element, the first back gate insulator, and the first channel region form a first resistor-capacitor (RC) circuit, and the second delay element, the second back gate insulator, and the second channel region form a second RC circuit.

    摘要: Device structures and design structures for passive devices that may be used as electrostatic discharge protection devices in fin-type field-effect transistor integrated circuit technologies. A device region is formed in a trench and is coupled with a handle wafer of a semiconductor-on-insulator substrate. The device region extends through a buried insulator layer of the semiconductor-on-insulator substrate toward a top surface of a device layer of the semiconductor-on-insulator substrate. The device region is comprised of lightly-doped semiconductor material. The device structure further includes a doped region formed in the device region and that defines a junction. A portion of the device region is laterally positioned between the doped region and the buried insulator layer of the semiconductor-on-insulator substrate. Another region of the device layer may be patterned to form fins for fin-type field-effect transistors.
