ABSTRACT:
The present invention is a method for manufacturing a semiconductor apparatus including a chip which is fabricated in large numbers on a wafer and has a plurality of information blocks. In the method, a unique information bit is written in a chip discrimination block of each chip within a shot, which is a segmented region of the wafer, by a fixed pattern method. In addition, an information bit uniquely given to each shot within the wafer is written by a mask shift method. Further, an information bit uniquely given to each wafer is written in a wafer discrimination block of the chip which is fabricated on the wafer by the mask shift method and mask combination method.
