Abstract:
1. A semiconductor device comprising: a first semiconductor chip disposed with a circuit formation surface of the first semiconductor chip facing downward; a second semiconductor chip above which the first semiconductor chip is mounted such that the circuit formation surface of the first semiconductor chip faces a circuit formation surface of the second semiconductor chip; a base on which the second semiconductor chip is mounted; a first interconnect having a ring shape and formed on the circuit formation surface of the second semiconductor chip to overlap an outer circumference or part of a circumferential section of a mounting region above which the first semiconductor chip is mounted; and a second interconnect formed in a region in which the first semiconductor chip faces the second semiconductor chip, the second interconnect extending from the first interconnect to a center section of the first semiconductor chip or the second semiconductor chip, wherein at the center section of the first semiconductor chip or the second semiconductor chip, the second interconnect is electrically connected to a connection terminal on the circuit formation surface of the first semiconductor chip or the second semiconductor chip, and the first interconnect and the second interconnect are power supply interconnects or ground interconnects.
