    摘要： The present invention generally relates to a method for improving inversion layer mobility and providing low defect density in a semiconductor device based upon a silicon carbide (SiC) substrate. More specifically, the present invention provides a method for the manufacture of a semiconductor device based upon a silicon carbide substrate and comprising an oxide layer comprising incorporating at least one additive into the atomic structure of the oxide layer. Semiconductor devices, such as MOSFETS, based upon a substrate treated according to the present method are expected to have inversion layer mobilities of at least about 60 cm2/Vs.

    摘要： A method of manufacturing a heterostructure device is provided that includes implantation of ions into a portion of a surface of a multi-layer structure. Iodine ions are implanted between a first region and a second region to form a third region. A charge is depleted from the two dimensional electron gas (2DEG) channel in the third region to form a reversibly electrically non-conductive pathway from the first region to the second region. On applying a voltage potential to a gate electrode proximate to the third region allows electrical current to flow from the first region to the second region.

    摘要： A heterostructure device or article includes a carrier transport layer, a back channel layer and a barrier layer. The carrier transport layer has a first surface and a second surface opposing to the first surface. The back channel layer is secured to the first surface of the carrier transport layer and the barrier layer is secured to the second surface of the carrier transport layer. Each of the carrier transport layer, the back channel layer and the barrier layer comprises an aluminum gallium nitride alloy. The article further includes a 2D electron gas at an interface of the second surface of the carrier transport layer and a surface of the barrier layer. The 2D electron gas is defined by a bandgap differential at an interface, which allows for electron mobility. A system includes a heterostructure field effect transistor that includes the article.

    摘要： A vertical heterostructure field effect transistor including a first layer having a first material, and the first material having a hexagonal crystal lattice structure defining a first bandgap and one or more non-polar planes is provided. The transistor further includes a second layer that is adjacent to the first layer having a second material. Further, the second layer has a first surface and a second surface, and a portion of the second layer first surface is coupled to the surface of the first layer to form a two dimensional charge gas and to define a first region. The second material may have a second bandgap that is different than the first bandgap. Furthermore, the transistor may include a conductive layer that is disposed in the trench and is interposed between the first region and a second region that is not in electrical communication with the first region if no electrical potential is applied to the conductive layer, and an electrical potential applied to the conductive layer allows electrical communication from the first region to the second region.
