Layered chip package and method of manufacturing same
A layered chip package includes a main body and wiring. The main body includes: a main part having a top surface and a bottom surface and including three or more layer portions stacked on one another; a plurality of first terminals disposed on the top surface of the main part; and a plurality of second terminals disposed on the bottom surface of the main part. Each layer portion includes a semiconductor chip having first and second surfaces, and a plurality of electrodes electrically connected to the wiring. The plurality of electrodes are disposed on a side of the first surface of the semiconductor chip. A first layer portion located closest to the top surface of the main part and a second layer portion located closest to the bottom surface of the main part are arranged so that the second surfaces of their respective semiconductor chips face toward each other. The plurality of first terminals are formed by using the plurality of electrodes of the first layer portion. The plurality of second terminals are formed by using the plurality of electrodes of the second layer portion.
