    摘要： Disclosed is an integrated circuit with multiple semiconductor fins having different widths and variable spacing on the same substrate. The method of forming the circuit incorporates a sidewall image transfer process using different types of mandrels. Fin thickness and fin-to-fin spacing are controlled by an oxidation process used to form oxide sidewalls on the mandrels, and more particularly, by the processing time and the use of intrinsic, oxidation-enhancing and/or oxidation-inhibiting mandrels. Fin thickness is also controlled by using sidewalls spacers combined with or instead of the oxide sidewalls. Specifically, images of the oxide sidewalls alone, images of sidewall spacers alone, and/or combined images of sidewall spacers and oxide sidewalls are transferred into a semiconductor layer to form the fins. The fins with different thicknesses and variable spacing can be used to form a single multiple-fin FET or, alternatively, various single-fin and/or multiple-fin FETs.

    摘要： A method is described for fabricating and antifuse structure (100) integrated with a semiconductor device such as a FINFET or planar CMOS devise. A region of semiconducting material (11) is provided overlying an insulator (3) disposed on a substrate (10); an etching process exposes a plurality of corners (111–114) in the semiconducting material. The exposed corners are oxidized to form elongated tips (111t–114t) at the corners; the oxide (31) overlying the tips is removed. An oxide layer (51), such as a gate oxide, is then formed on the semiconducting material and overlying the corners; this layer has a reduced thickness at the corners. A layer of conducting material (60) is formed in contact with the oxide layer (51) at the corners, thereby forming a plurality of possible breakdown paths between the semiconducting material and the layer of conducting material through the oxide layer. Applying a voltage, such as a burn-in voltage, to the structure converts at least one of the breakdown paths to a conducting path (103, 280).

A doped semiconductor spacer or plug laterally abutting sidewalls of the second metal line and vertically abutting a top surface of the first metal line provides a resistive link between the first and second metal lines. In another embodiment, another BEOL resistive structure comprises a first metal line and a second metal line are embedded in a dielectric layer. A doped semiconductor spacer or plug laterally abutting the sidewalls of the first and second metal lines provides a resistive link between the first and second metal lines.

    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.

    摘要： 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.
