    摘要: A method for forming a transistor includes providing a patterned gate stack disposed on a III-V substrate and having sidewall spacers formed on sides of the patterned gate stack, the III-V substrate including source/drain regions adjacent to the sidewall spacers and field oxide regions formed adjacent to the source/drain regions. The method includes growing raised source/drain regions on the source/drain regions, the grown raised source/drain regions including III-V semiconductor material, and growing metal contacts on the grown raised source/drain regions. Another method for forming a transistor includes providing a patterned gate stack disposed on a III-V substrate and having sidewall spacers formed on sides of the patterned gate stack, the III-V substrate including source/drain regions adjacent to the sidewall spacers and field oxide regions formed adjacent to the source/drain regions. The method includes growing metal contacts on the source/drain regions. Transistors and computer program products are also disclosed.

    摘要: Techniques for employing different channel materials within the same CMOS circuit are provided. In one aspect, a method of fabricating a CMOS circuit includes the following steps. A wafer is provided having a first semiconductor layer on an insulator. STI is used to divide the first semiconductor layer into a first active region and a second active region. The first semiconductor layer is recessed in the first active region. A second semiconductor layer is epitaxially grown on the first semiconductor layer, wherein the second semiconductor layer comprises a material having at least one group III element and at least one group V element. An n-FET is formed in the first active region using the second semiconductor layer as a channel material for the n-FET. A p-FET is formed in the second active region using the first semiconductor layer as a channel material for the p-FET.

    摘要: Field Effect Transistors (FETs), Integrated Circuit (IC) chips including the FETs, and a method of forming the FETs and IC. FET locations define FET pedestals on a layered semiconductor wafer that may include a III-V semiconductor surface layer, e.g., Gallium Arsenide (GaAs), and a buried layer, e.g., Aluminum Arsenide (AlAs). A dielectric material, e.g., Aluminum Oxide (AlO), surrounds pedestals at least in FET source/drain regions. A conductive cap caps channel sidewalls at opposite channel ends. III-V on insulator (IIIVOI) devices form wherever the dielectric material layer is thicker than half the device length. Source/drain contacts are formed to the caps and terminate in/above the dielectric material in the buried layer.

    摘要: Field Effect Transistors (FETs), Integrated Circuit (IC) chips including the FETs, and a method of forming the FETs and IC. FET locations are defined on a layered semiconductor wafer. The layered semiconductor wafer preferably includes a III-V semiconductor surface layer, e.g., Gallium Arsenide (GaAs), and a buried layer, e.g., Aluminum Arsenide (AlAs). Portions of the buried layer are converted to dielectric material, e.g., Aluminum Oxide (AlO), at least beneath FET source/drain regions. The converted dielectric material may extend completely under the FET. Source/drain contacts are formed to FETs above the dielectric material in the buried layer.
