Abstract:
1. A semiconductor module comprising: semiconductor chip mounting wiring boards, at least one of the semiconductor chip mounting boards including an insulating resin substrate including a center and a periphery, and having provided nearly in the center on one side thereof a semiconductor chip mounting area, first conductive bumps formed in the semiconductor chip mounting area, openings in the insulating substrate outside the semiconductor chip mounting area, wiring patterns extending from the first conductive bumps over the openings toward the periphery of the insulating resin substrate, viaholes formed, on the other side of the insulating resin substrate, from a conductive substance filled in the openings leading to the wiring patterns, and second conductive bumps electrically connected to the viaholes and projecting from the other side of the insulating resin substrate; and interlayer members each formed from an insulating resin substrate including a center and having formed nearly in the center thereof an opening to receive the semiconductor chip, and a conductive post formed from a conductive substance filled in a through-hole formed through the insulating resin substrate of the interlayer members and projecting from either side of the insulating resin substrate of the interlayer members; and the semiconductor chip mounting wiring boards and the interlayer members are alternately stacked with an adhesive applied therebetween and the stack being hot-pressed.
