Composite layered chip package

A composite layered chip package comprising a first subpackage and a second subpackage, the second subpackage being stacked on and electrically connected to the first subpackage, wherein:

• each of the first and second subpackages includes a main body and wiring;
• the main body includes:
• a main part including at least one layer portion and having a top surface and a bottom surface;
• 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;
• the plurality of first terminals and the plurality of second terminals are electrically connected to the wiring;
• the at least one layer portion includes a semiconductor chip;
• the plurality of first terminals of the first subpackage and those of the second subpackage are in the same layout;
• the plurality of second terminals of the first subpackage and those of the second subpackage are in the same layout;
• the first subpackage and the second subpackage are arranged in a specific relative positional relationship with each other, the specific relative positional relationship being different from a reference relative positional relationship, the reference relative positional relationship being such that, when viewed in a direction perpendicular to the top surface of the main part of the second subpackage, the plurality of first terminals of the first subpackage and the plurality of first terminals of the second subpackage coincide with each other in position while the plurality of second terminals of the first subpackage and the plurality of second terminals of the second subpackage coincide with each other in position, the specific relative positional relationship being such that, with respect to the reference relative positional relationship, the second subpackage is displaced in a direction parallel to the top surface of the main part of the second subpackage;
• the plurality of first terminals and the plurality of second terminals are shaped and arranged so that a plurality of pairs of first and second terminals are formed regardless of whether in the reference relative positional relationship or the specific relative positional relationship, each of the plurality of pairs of first and second terminals being made up of one of the plurality of first terminals of the first subpackage and one of the plurality of second terminals of the second subpackage that are in contact with each other;
• and
• combinations of the first and second terminals making up the plurality of pairs of first and second terminals in the specific relative positional relationship are different from those in the reference relative positional relationship.
