Abstract:
A method for manufacturing a silicon carbide device includes providing a silicon carbide wafer and manufacturing a mask layer on top of the silicon carbide wafer. Further, the method includes structuring the mask layer at an edge of a silicon carbide device to be manufactured, so that the mask layer includes a bevel at the edge of the silicon carbide device to be manufactured. Additionally, the method includes etching the mask layer and the silicon carbide wafer by a mutual etching process, so that the bevel of the mask layer is reproduced at the edge of the silicon carbide device.
