Abstract:
1. A semiconductor device comprising: a chip stacked body where a plurality of semiconductor chips are stacked, and penetration electrodes respectively formed in the plurality of semiconductor chips are electrically interconnected in stacking order of the plurality of semiconductor chips; a first support member that is disposed to face a first semiconductor chip that is a semiconductor chip formed in one end of the chip stacked body in a stacking direction of the plurality of semiconductor chips, and the first support member including electrodes electrically connected to the penetration electrodes of the first semiconductor chip; and a wiring board that is disposed to face a second semiconductor chip that is a semiconductor chip formed in an end opposed to the one end of the chip stacked body in the stacking direction of the plurality of semiconductor chips, and the wiring board including external electrodes on a surface opposed to a surface facing the second semiconductor chip to be electrically connected to the penetration electrodes of the second semiconductor chip, wherein a material for the first support member is similar to that for the plurality of semiconductor chips.
