Abstract
This invention provides a multi-pin semiconductor device as a low-cost flip-chip BGA. In the flip-chip BGA, a plurality of signal bonding electrodes in a peripheral area of the upper surface of a multilayer wiring substrate are separated into inner and outer ones and a plurality of signal through holes coupled to a plurality of signal wirings drawn inside are located between a plurality of rows of signal bonding electrodes and a central region where a plurality of bonding electrodes for core power supply are located so that the chip pad pitch can be decreased and the cost of the BGA can be reduced without an increase in the number of layers in the multilayer wiring substrate.
