Abstract:
1. A semiconductor device comprising: a circuit substrate including an insulating layer, a plurality of interconnections forming first interconnection layers provided on an upper surface side of the insulating layer, a plurality of interconnections forming second interconnection layers provided on a lower surface side of the insulating layer, and a plurality of vias penetrating from the upper surface to the lower surface of the insulating layer; a semiconductor element mounted on the upper surface side of the circuit substrate; a sealing resin layer provided on the upper surface of the circuit substrate and sealing the semiconductor element; and a conductive shielding layer covering the sealing resin layer and part of an end portion of the circuit substrate, some of the plurality of vias and the conductive shielding layer being electrically connected, some of outermost peripheral ones of the plurality of interconnections forming the second interconnection layers being electrically connected to an external connection terminal capable of becoming a ground potential, and other of the outermost peripheral ones of the plurality of interconnections forming the second interconnection layers being electrically connected to a signal line.
