Abstract

In a pin grid array type multi-chip module structure comprised of a ceramic multi-layer wiring board having the top surface on which a plurality of semiconductor devices are carried, divisional board areas each having the same size are respectively allotted to individual semiconductor devices of the same type. Within respective divisional board areas, the positional relation between the array arrangement of connecting pads on the top surface for connection to the semiconductor devices and the array arrangement of I/O pins on the bottom surface of the board is so determined as to be constant. Metallized patterns inside the board which are to be connected power supply I/O pins and ground I/O pins are made constant for respective divisional board areas allotted to individual semiconductor devices of the same type.
