Abstract:
1. A semiconductor integrated circuit device comprising: a semiconductor chip formed with a semiconductor integrated circuit; at least one pair of previous-stage power supply terminals provided on the semiconductor chip and connected to a power supply line; a plurality of pairs of subsequent-stage power supply terminals provided on the semiconductor chip and connected to the power supply line connected commonly to the at least one pair of previous-stage power supply terminals; at least one previous-stage line providing a connection between the at least one pair of previous-stage power supply terminals; subsequent-stage lines equal in number to the plurality of pairs of subsequent-stage power supply terminals and each providing a connection between the corresponding one of the plurality of pairs of subsequent-stage power supply terminals; a previous-stage center power supply terminal disposed between the at least one pair of previous-stage power supply terminals and connected to a power supply line other than the foregoing power supply line; and a plurality of subsequent-stage center power supply terminals each disposed between the corresponding one of the plurality of pairs of subsequent-stage power supply terminals and connected to the power supply line connected commonly to the previous-stage center power supply terminal, the at least one pair of previous-stage power supply terminals and the plurality of pairs of subsequent-stage power supply terminals being connected to each other to form a closed circuit when they are mounted on a mounting board, and the previous-stage center power supply terminal and the plurality of subsequent-stage center power supply terminals being connected to each other when they are mounted on the mounting board.
