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.
摘要翻译：场效应晶体管中的沟道深度由包括在半导体材料的层或衬底内形成的不连续膜或层的层内结构限制。因此，可以以SOI或UT-SOI技术的方式控制通道深度，但是具有较便宜的衬底和更大的通道深度控制的灵活性，同时避免SOI技术的浮体效应特性。不连续膜的轮廓或横截面形状可以被控制为奥格或阶梯形状，以改善短通道效应，并且在不增加电容的情况下降低源极/漏极和延伸电阻。也可以选择用于不连续膜的材料以在衬底或层内从晶体管沟道施加应力，并提供增加的这种应力水平以增加载流子迁移率。携带者的流动性可能会与其他有利的影响相结合。

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.
