PURPOSE:To obtain the substrate, in which the directions of arrangement of functional blocks to be superposed are reversely allowed in the four directions in X, Y each axial-symmetry form and has high flexibility, by arranging an active element, a passive element, etc. and cell constitutional elements with a power supply and a ground power supply in point-symmetry form to the center of a cell. CONSTITUTION:The unit cell 2 is constituted by four transistors 3 (collectors 4, bases 6 and emitters 5) and the power supplies 8 and the ground power supply 7, and these cell constitutional elements 3, 7, 8 are disposed in point-symmetry form to the center 0 in this example. The functional block 9 is constituted by one cell, a specific function is displayed by wiring 10 and a through-hole 11, and input terminals 13 (specific positions of the bases) and output terminals 12 (specific positions of the collectors) are provided. The input/output terminals 13, 12 serve as starting points and end points for connection respectively among the functional blocks 9 when kinds are designed. |
