    摘要: A transistor component having a shielding structure. One embodiment provides a source terminal, a drain terminal and control terminal. A source zone of a first conductivity type is connected to the source terminal. A drain zone of the first conductivity type is connected to the drain terminal. A drift zone is arranged between the source zone and the drain zone. A junction control structure is provided for controlling a junction zone in the drift zone between the drain zone and the source zone, at least including one control zone. A shielding structure is arranged in the drift zone between the junction control structure and the drain zone and at least includes a shielding zone of a second conductivity type being complementarily to the first conductivity type. The shielding zone is connected to a terminal for a shielding potential. The at least one control zone and the at least one shielding zone have different geometries or different orientations in a plain that is perpendicular to a current flow direction of the component.

    摘要: A method for treating a surface on an SiC semiconductor body produced by epitaxy. According to the method, the parts of the epitactic layer that are deposited in the final phase of the epitaxy are removed by etching and a wet chemical treatment is then carried out in order to remove a thin natural oxide on the surface. Alternatively, a metal layer configured as a Schottky contact and/or as an ohmic contact can also be applied to the surface immediately after the removal process.
