    摘要: A method and structure in which Ge-based semiconductor devices such as FETs and MOS capacitors can be obtained are provided. Specifically, the present invention provides a method of forming a semiconductor device including a stack including a dielectric layer and a conductive material located on and/or within a Ge-containing material (layer or wafer) in which the surface thereof is non-oxygen chalcogen rich. By providing a non-oxygen chalcogen rich interface, the formation of undesirable interfacial compounds during and after dielectric growth is suppressed and interfacial traps are reduced in density.

    摘要: A semiconductor-containing heterostructure including, from bottom to top, a III-V compound semiconductor buffer layer, a III-V compound semiconductor channel layer, a III-V compound semiconductor barrier layer, and an optional, yet preferred, III-V compound semiconductor cap layer is provided. The barrier layer may be doped, or preferably undoped. The III-V compound semiconductor buffer layer and the III-V compound semiconductor barrier layer are comprised of materials that have a wider band gap than that of the III-V compound semiconductor channel layer. Since wide band gap materials are used for the buffer and barrier layer and a narrow band gap material is used for the channel layer, carriers are confined to the channel layer under certain gate bias range. The inventive heterostructure can be employed as a buried channel structure in a field effect transistor.

    摘要: The invention addresses the problem of creating a high-speed, high-efficiency photodetector that is compatible with Si CMOS technology. The structure consists of a Ge absorbing layer on a thin SOI substrate, and utilizes isolation regions, alternating n- and p-type contacts, and low-resistance surface electrodes. The device achieves high bandwidth by utilizing a buried insulating layer to isolate carriers generated in the underlying substrate, high quantum efficiency over a broad spectrum by utilizing a Ge absorbing layer, low voltage operation by utilizing thin a absorbing layer and narrow electrode spacings, and compatibility with CMOS devices by virtue of its planar structure and use of a group IV absorbing material. The method for fabricating the photodetector uses direct growth of Ge on thin SOI or an epitaxial oxide, and subsequent thermal annealing to achieve a high-quality absorbing layer. This method limits the amount of Si available for interdiffusion, thereby allowing the Ge layer to be annealed without causing substantial dilution of the Ge layer by the underlying Si.
