Abstract:
A composite layered chip package includes a plurality of subpackages stacked on each other. Each subpackage includes a main body and wiring. The main body includes a main part including a plurality of layer portions, and further includes first terminals and second terminals that are disposed on top and bottom surfaces of the main part, respectively. The wiring is electrically connected to the first and second terminals. The number of the plurality of layer portions included in the main part is the same for all the plurality of subpackages, and the plurality of layer portions in every subpackage include at least one first-type layer portion. In each of at least two of the subpackages, the plurality of layer portions further include at least one second-type layer portion. The first-type layer portion includes a semiconductor chip connected to the wiring, whereas the second-type layer portion includes a semiconductor chip not connected to the wiring.
