A feeder design is manufactured as a structure in a SIC semiconductor material comprising at least two p-type grids in an n-type SiC material (3), comprising at least one epitaxially grown p-type region, wherein an Ohmic contact is applied on the at least one epitaxially grown p-type region, wherein an epitaxially grown n-type layer is applied on at least a part of the at least two p-type grids and the n-type SiC material (3) wherein the at least two p-type grids (4, 5) are applied in at least a first and a second regions at least close to the at least first and second corners respectively and that there is a region in the n-type SiC material (3) between the first and a second regions without any grids.
