Abstract
A semiconductor device is provided that reduces the number of external power terminals. The device is intended for a flip-chip type BGA (ball grid array) package. On the surface of the packet substrate are a plurality of output circuits each outputting a signal formed by an internal circuit, a first voltage supply electrode which supplies an operating voltage to the internal circuit and a plurality of second voltage supply electrodes which supply operating voltages to the output circuits. On the back surface of the package substrate are external terminals and a plurality of wiring layers.
