Layered chip package and method of manufacturing same
A layered chip package includes a main body including a plurality of layer portions, and wiring disposed on a side surface of the main body. Each layer portion includes a semiconductor chip, an insulating portion covering at least one side surface of the semiconductor chip, and a plurality of electrodes connected to the semiconductor chip. The insulating portion has an end face located at the side surface of the main body on which the wiring is disposed. Each electrode has an end face surrounded by the insulating portion and located at the side surface of the main body on which the wiring is disposed. To manufacture the layered chip package, a layered chip package substructure is fabricated by: processing a semiconductor wafer to form a plurality of pre-semiconductor-chip portions aligned; forming at least one groove extending to be adjacent to at least one of the pre-semiconductor-chip portions; forming an insulating layer to fill the groove; and forming the electrodes.
