  • Patent number: 12119329
    Abstract: The present disclosure relates to a semiconductor package and a manufacturing method thereof. The method includes stacking semiconductor chips using a thermo-compression bonding (TCB) method, where defects are minimized for increased reliability. The semiconductor package includes an interface chip including a first test pad, a bump pad provided inside the first test pad, and a first through silicon via (TSV) provided between the first test pad and the bump pad; at least one memory chip, which is stacked on the interface chip and includes a second test pad, a dummy pad provided inside the second test pad, and a second TSV provided between the second test pad and the dummy pad; and an adhesive layer provided between the interface chip and the at least one memory chip. wherein no bump is provided on the first test pad and the second test pad.

  • Patent number: 11658160
    Abstract: A semiconductor package may include a package substrate, semiconductor chips, signal bumps, and first and second heat dissipation bumps. The semiconductor chips may be stacked on an upper surface of the package substrate, have first and second regions having different heat dissipation efficiencies. The second temperature may be higher than the first temperature. The signal bumps may be arranged between the semiconductor chips. The first heat dissipation bumps may be arranged between the semiconductor chips in the first region by a first pitch. The second heat dissipation bumps may be arranged between the semiconductor chips in the second region by a second pitch narrower than the first pitch. Heat generated from the second region of the semiconductor chips may be dissipated through the second heat dissipation bumps, which may be relatively closely arranged with each other.
