MASTER-SLICE SEMICONDUCTOR DEVICE

PURPOSE:To make the position of a power-supply terminal on a chip freely correspond to the positions of power-supply terminals on various cases by correspondingly arranging an element group required for constituting input/output circuits to the power supply terminals. CONSTITUTION:Terminals 112, 115 for signals assigned to input terminals are fitted to one part 111 of a chip shell. 113 Is assigned to a power supply and 114 to GND in power supply terminals 112-114. 116-119 Represent the element group for the input circuit, 120 represents the second wiring at the same potential as the terminal 114, and 121 represents the second wiring at the same potential as the terminal 113, reaches the first wiring 122 through openings 123-126, and further reaches the second wiring 135 at the same potential as the terminal 113 through openings 127-132. Wiring for the input circuit is not connected in the element groups 117, 118 for the input circuit at that time, and only the power-supply wiring of the power supply 135 and the GND 120 passes at the same positions. Accordingly, the power-supply terminals are made correspond freely to the positions of the power-supply terminals of various cases because the terminals can be changed into power-supply terminals at the arbitrary positions of the terminals on the chip.
