    摘要: A susceptor assembly for use in an epitaxial growth reactor for growing silicon carbide epitaxial layers. The susceptor assembly is rotatable about a central axis and includes a plurality of cavities each for receiving a wafer holder. A plurality of gas passageways leading to respective cavities, carries gas for levitating and rotating the wafer holders in their respective cavities. All of the gas passageways in the susceptor assembly are non-radially oriented.

    摘要: A high Q monolithic metal-insulator-metal (MIM) capacitor utilizing a single crystal dielectric material. A dielectric membrane is epitaxially grown on a substrate. The membrane acts as an etch-stop when a backside etch is used to form a cavity in the substrate, resulting in a single crystal dielectric membrane spanning the cavity. Electrodes are formed on opposite surfaces of the membrane at the cavity location. For a shunt capacitor application, the bottom electrode is connected to the backside substrate metallization. For a series capacitor application, the bottom electrode is isolated from the backside metallization, but is connected to the topside circuitry through a via formed in the membrane. The membrane may consist of two dielectric layers, where the first layer is an etchstop material. In one embodiment the substrate and second dielectric layer are gallium arsenide and the first dielectric layer is aluminum gallium arsenide.

    摘要: A ceiling arrangement for a high temperature epitaxial growth reactor in which silicon carbide epitaxial layers may be grown. The ceiling includes an upper layer of carbon foam and a lower layer of graphite bonded thereto. A support structure for the ceiling is coupled to a nozzle assembly, holding a gas delivering nozzle. The support structure has a lower flange portion which includes an upwardly extending projection defining a knife edge upon which the ceiling rests. The arrangement minimizes unwanted heat transfer from the ceiling to the nozzle assembly and nozzle.
