摘要:
Device structures for a metal-oxide-semiconductor field effect transistor (MOSFET) that is suitable for operation at relatively high voltages and methods of forming same. The MOSFET, which is formed using a semiconductor-on-insulator (SOI) substrate, includes a channel in a semiconductor body that is self-aligned with a gate electrode. The gate electrode and semiconductor body, which are both formed from the monocrystalline SOI layer of the SOI substrate, are separated by a gap that is filled by a gate dielectric layer. The gate dielectric layer may be composed of thermal oxide layers grown on adjacent sidewalls of the semiconductor body and gate electrode, in combination with an optional deposited dielectric material that fills the remaining gap between the thermal oxide layers.

Device and design structures for memory cells in a non-volatile random access memory (NVRAM) and methods for fabricating such device structures using complementary metal-oxide-semiconductor (CMOS) processes. The device structure, which is formed using a semiconductor-on-insulator (SOI) substrate, includes a floating gate electrode, a semiconductor body, and a control gate electrode separated from the semiconductor body by the floating gate electrode. The floating gate electrode, the control gate electrode, and the semiconductor body, which are both formed from the monocrystalline SOI layer of the SOI substrate, are respectively separated by dielectric layers. The dielectric layers may each be composed of thermal oxide layers grown on confronting sidewalls of the semiconductor body, the floating gate electrode, and the control gate electrode. An optional deposited dielectric material may fill any remaining gap between either pair of the thermal oxide layers.

In one embodiment, the gate electrode of the second field effect transistor is a remaining portion of the top semiconductor layer. In another embodiment, the gate electrode of the second field effect transistor is formed concurrently with the gate electrode of the first field effect transistor by deposition and patterning of a gate electrode layer. The first field effect transistor may be a high performance device and the second field effect transistor may be a high voltage device.

摘要:
A doped contact region having an opposite conductivity type as a bottom semiconductor layer is provided underneath a buried insulator layer in a bottom semiconductor layer. At least one conductive via structure extends from an interconnect-level metal line through a middle-of-line (MOL) dielectric layer, a shallow trench isolation structure in a top semiconductor layer, and a buried insulator layer and to the doped contact region. The doped contact region is biased at a voltage that is at or close to a peak voltage in the RF switch that removes minority charge carriers within the induced charge layer. The minority charge carriers are drained through the doped contact region and the at least one conductive via structure. Rapid discharge of mobile electrical charges in the induce charge layer reduces harmonic generation and signal distortion in the RF switch. A design structure for the semiconductor structure is also provided.
