    摘要: A silicon on insulator transistor is disclosed which has a Schottky contact to the body. The Schottky contact may be formed on the source and/or drain side of the gate conductor. A spacer, with at least a part thereof being disposable, is formed on the sidewalls of the gate conductor. Extension regions are provided in the substrate which extend under the spacer and the gate conductor. Source and drain diffusion regions are implanted into the substrate adjacent to the extension regions. The disposable part of the spacer is then removed to expose a portion of the extension region. A metal layer is formed at least in the extension regions, resulting in the Schottky contact.

    摘要: A planar silicon-on-insulator (SOI) structure and a process for fabricating the structure. The SOI structure has a silicon wafer, an oxide layer, and a silicon layer. Trenches are formed, extending from the top surface of the structure to the silicon wafer, and are filled with a semiconductor. The trenches have a top, a bottom, and side walls. The side walls have side-wall silicon portions. The side-wall silicon portions of the trench side walls are covered by trench side-wall oxide layers. A protective side wall extends over the trench side walls and trench side-wall oxide layers from the trench top to the trench bottom.

    摘要: A process for making a SOI region and a bulk region in a semiconductor device. The process includes providing a SOI structure. The SOI structure has a thin silicon layer, a buried insulating oxide layer underlying the thin silicon layer, and a silicon substrate underlying the buried insulating oxide layer. Next, a nitride layer is deposited on top of the SOI structure. The SOI structure is exposed by selectively etching portions of the nitride layer. The portion of the nitride layer which is not etched forms the SOI region. The silicon substrate is exposed by selectively etching the remaining portion of the exposed SOI structure. An epitaxial layer is grown in top of the exposed silicon substrate to form the bulk region. The nitride portion above the SOI structure is finally removed.

    摘要: A finFET device is provided. The finFET device includes a BOX layer, fin structures located over the BOX layer, a gate stack located over the fin structures, gate spacers located on vertical sidewalls of the gate stack, an epi layer covering the fin structures, source and drain regions located in the semiconductor layers of the fin structures, and silicide regions abutting the source and drain regions. The fin structures each comprise a semiconductor layer and extend in a first direction, and the gate stack extends in a second direction that is perpendicular. The gate stack comprises a high-K dielectric layer and a metal gate, and the epi layer merges the fin structures together. The silicide regions each include a vertical portion located on the vertical sidewall of the source or drain region.
