  • Patent number: 8889483
    Abstract: A method of manufacturing a semiconductor device in one exemplary embodiment includes preparing a first substrate and a second substrate, the first substrate including a bump electrode group formed of bump electrodes arrayed with a certain pitch, the number of bump electrodes along a first direction being larger than the number of bump electrodes along a second direction perpendicular to the first direction; joining the first substrate and the second substrate to each other through the bump electrodes so that a gap is formed between the first substrate and the second substrate; and filling the gap with a mold resin by causing the mold resin to flow in the gap from an edge of the first substrate along the second direction of the bump electrode group.
    Type: Grant

  • Patent number: 8461690
    Abstract: A semiconductor device includes a chip stacked body where a plurality of semiconductor chips are stacked, and penetration electrodes respectively formed in the semiconductor chips are electrically interconnected in stacking order of the semiconductor chips, a first support member that is disposed to face a first semiconductor chip formed in one end of the chip stacked body, and 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 formed in an end opposed to the one end of the chip stacked body, and including external electrodes on a surface opposed to a surface facing the second semiconductor chip that is to be electrically connected to the penetration electrodes of the second semiconductor chip.
