Claim 13:
14. A semiconductor package, comprising:
a lower package including a lower substrate and at least one lower semiconductor chip;
an interposer substrate on the lower package, the interposer substrate including a plurality of holes that penetrate the interposer substrate; and
a thermal radiation structure on the interposer substrate, the thermal radiation structure including
a plurality of first portions in the holes of the interposer substrate and vertically overlapping the lower semiconductor chip, and
at least one second portions on a top surface of the interposer substrate and connected to the first portions,

wherein the thermal radiation structure is spaced apart from sidewalls of the holes of the interposer substrate and from a top surface of the lower semiconductor chip.
