Abstract

PURPOSE:To discriminate kinds electrically and easily by forming elements for distinguishing kinds at every each circuit unit of a semiconductor wafer with a large number of circuits of different kinds. CONSTITUTION:When a large number of the circuits of different kinds (such as X2 and Y6) are formed to the semiconductor wafer 1, the diodes 4 are fitted to Xs and the diodes 7 having rectifying property in the opposite direction of the diodes 4 to Ys at every each circuit unit, voltage is applied among pads 3 and 5 (3' and 5'), and the kinds of the circuit units are discriminated according to the existence of rectifying characteristics. Consequently, the kinds can easily by distinguished electrically by means of an automatic measuring machine.
