In a method of making an encircling groove (8) on the edge of a semiconductor slice (5) of a power semiconductor component, first of all the edge is surface-ground and then the groove (8) is ground in one operation by means of a form-grinding wheel (3) correspondingly contoured on the edge. An especially high output is achieved with diamond grinding wheels of appropriate grain size and suitable bond.
