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.
