Patent ID: 8394678

Claim:
A semiconductor chip stacked body, comprising: a plurality of chip sealing bodies, each of the chip sealing bodies including a semiconductor chip, which has a semiconductor integrated circuit, a pad and a conductive connecting material connecting the pad to an external device, and a resin sealing the semiconductor chip, each of the chip sealing bodies being shaped into a cubic form in which a portion of the conductive connecting material except an end portion located on an external device side and all surfaces of semiconductor chip is sealed by the resin and the end portion of the conductive connecting material located on the external device side is exposed from the cubic form; a wiring substrate which has a connection terminal; a conductive bonding wire used for side surface wiring which connects between chips, the conductive bonding wire connecting the end portions of the conductive connecting materials in the plurality of chip sealing bodies and the connection terminal respectively, the conductive bonding wire being a metal wire supplied from a wiring bonder; and a resin sealing material which seals the plurality of chip sealing bodies, the conductive bonding wire, and the wiring substrate, wherein the plurality of chip sealing bodies are stacked on the wiring substrate, and exposed end portions of the conductive connecting materials in the chip sealing bodies are conductively connected by the conductive bonding wire respectively.
