Abstract:
1. An electronic component containing substrate comprising: first and second wiring substrates; a plurality of electronic components which are mounted in a stacked fashion, the electronic components including a first electronic component mounted on a top surface of the first wiring substrate and a second electronic component mounted on the first electronic component; a plurality of solder balls which electrically connect the first and second wiring substrates and separate the first and second wiring substrates to provide a space for the first electronic component; and a sealing resin which fills and seals the space between the first and second wiring substrates for the first electronic component such that the sealing resin seals the first electronic component and the plurality of solder balls, wherein the second wiring substrate has an opening portion extending through the second wiring substrate from a top surface thereof to a bottom surface thereof for containing the second electronic component therein, and wherein the second electronic component is contained in the opening portion of the second wiring substrate such that an outer periphery of the second electronic component is surrounded by the opening portion, and the second electronic component is connected electrically to the top surface of the second wiring substrate by a wire bonding.
