    摘要: A field effect transistor (FET), integrated circuit (IC) chip including the FETs and a method of forming the FETS. Each FET includes a device gate along one side of a semiconductor (e.g., silicon) fin and a back bias gate along an opposite of the fin. Back bias gate dielectric differs from the device gate dielectric either in its material and/or thickness. Device thresholds can be adjusted by adjusting back bias gate voltage.

    摘要: Channel depth in a field effect transistor is limited by an intra-layer structure including a discontinuous film or layer formed within a layer or substrate of semiconductor material. Channel depth can thus be controlled much in the manner of SOI or UT-SOI technology but with less expensive substrates and greater flexibility of channel depth control while avoiding floating body effects characteristic of SOI technology. The profile or cross-sectional shape of the discontinuous film may be controlled to an ogee or staircase shape to improve short channel effects and reduce source/drain and extension resistance without increase of capacitance. Materials for the discontinuous film may also be chosen to impose stress on the transistor channel from within the substrate or layer and provide increased levels of such stress to increase carrier mobility. Carrier mobility may be increased in combination with other meritorious effects.

    摘要: A multi-gate device has a high-k dielectric layer for a top channel of the gate and a protective layer for use in a finFET device. The high-k dielectric layer is placed on the top surface of the channel of the finFET and may reduce or eliminate silicon consumption in the channel. The use of the high-k dielectric layer on the top surface reduces hysteresis and mobility degradation associated with high-k dielectrics. The protection layer may protect the high-k dielectric layer during an etching process.
