    摘要: A component is produced on a substrate made of SiC. The component has at least one ohmic contact and at least one Schottky contact. The component is brought to a temperature of more than 1300° C. at least during the growth of an epitaxial layer. To ensure that the production of the ohmic contact does not lead to impairment of other structures on the component and that the ohmic contact, for its part, is insensitive with respect to later method steps at high temperatures, the first metal is applied to the substrate for the ohmic contact before the epitaxial layer is grown.

    摘要: A device for producing a silicon carbide (SiC) single crystal contains a crucible having a storage region for holding a stock of solid SiC and having a crystal region for holding a SiC seed crystal. An insert made from glassy carbon is disposed in the crucible. In the method, solid SiC is sublimed as a result of the stock being heated and SiC in the gas phase is generated, which is conveyed to the SiC seed crystal, on which it grows as an SiC single crystal. A heat flux is controlled by an insert made from glassy carbon.

    摘要: A process gas stream (2) is generated, from which SiC is deposited on a substrate (4) by means of CVD. Furthermore, a second gas stream (3) of an inert gas is generated, which substantially surrounds the process gas stream (2) in its direction of flow. This results in a higher yield of the process gases.

    摘要: In the manufacture of semiconductor components, a SiC single crystal is exposed, during storage or transport between two process steps, to an oxygen-containing gas atmosphere, for example air. In order to prevent an oxide coating from forming on the SiC surface of the SiC single crystal, a carbon coating which does not react chemically with oxygen, preferably a graphite coating, is produced on said SiC surface.
