Claim 1
Independent Claim
146 words
METHOD OF PRODUCING SEMICONDUCTOR BODIES OF RELATIVELY SMALL AREA BY SERVING THEM FROM RELATIVELY LARGE SEMICONDUCTOR PLATES, WHICH COMPRISES THE STEPS OF ATTACHING AT LEAST ONE LARGE SEMICONDUCTOR PLATE BY ONE OF ITS FACES TO AN ADHESIVELY COATED SURFACE OF A DEFORMABLE FOIL, SCORING SEVERANCE TRACES IN THE EXPOSED FACE OF THE ADHERING PLATE IN A TRACE PATTERN CORRESPONDING TO THE PERIMETERS OF THE SMALL AREA BODIES TO BE OBTAINED, PLACING THE FOIL ONTO A SOFT PAD OF ELASTIC MATERIAL WITH THE SCORED FACE OF THE ADHERING PLATE ENGAGING THE PAD, PASSING A ROLLER UNDER PRESSURE OVER THE REAR SURFACE OF THE FOIL SO AS TO BEND THE FOIL AND FORM BREAKS IN THE PLATE ALONG THE TRACES AND SIMULTANEOUSLY PRESS THE PLATE INTO THE SOFT PAD SO THAT A PORTION OF THE ELASTIC MATERIAL OF THE PAD IS WEDGED INTO THE BREAKS ALONG THE TRACES.
