Abstract
A semiconductor device has pluralities of grid array terminals forming a grid array structure, e.g. a BGA structure, in which the output end of a built-in switch circuit is connected to multiple terminals of the grid array structure, thereby reducing the current that flows through each of the multiple terminals below a permissible level and minimizing the heat due to contact resistances of the multiple terminals in contact with the IC socket of the semiconductor device. Each pair of nearest neighbors of the multiple terminals is interposed by at least one further array terminal. The multiple terminals are all located at the outermost peripheral terminal positions of the grid array structure. Thus, the heat generated in the respective multiple terminals connected to the switch circuit is reduced, thereby minimizing the possibility of hazardous melting of the terminals.
