PURPOSE:To enhance the utility efficiency of a circular semiconductor wafer by setting improper portions occurred at the peripheral edge of the wafer at complementary relation when mounting a plurality of blocks having circuit function such as transistors or the like on a bearer by dividing them into two or four segments equally after providing the blocks even on the peripheral edge of the wafer when forming the blocks on the wafer. CONSTITUTION:When a plurality of circuit blocks A each having transistor, resistors and capacitors as circuit functions are formed on a circular semiconductor wafer, a circuit block A improper even in shape is also formed on the peripheral edge of the wafer to be normally abandoned. When the wafer is then divided into two or four segments and the divided wafers B, C are mounted on a bearer 1, the improper circuits A are so arranged and connected to become complementary relation among the divided wafers. Thus, the peripheral edge of the wafer may be used to thereby improve the utility efficiency of the wafer. |
