    摘要: The invention relates to a method in which proton or ion implantation is used for restructuring a silicon carbide region from being conductive to being resistive and wherein this implantation method is used for manufacturing a semiconductor device which comprises a p-n junction where both the p-conductive and the n-conductive layers are designed as doped layers of silicon carbide (SiC), whereby the implantation method is used for at least one of the steps passivation of a silicon carbide surface of the device with a semi-insulating layer, definition of the area of the p-n junction during manufacture, termination of the edges of the p-n junction by means of a semi-insulating layer, creation of a positive edge angle at the edge of the p-n junction, and insulation of different devices from one another during manufacture of a plurality of devices on one and the same wafer of silicon carbide, wherein the invention also relates to the implantation method proper.
