Patent ID: 6980438

Claim:
A semiconductor package having a heat dissipating structure, comprising: a substrate having a first surface and a second surface opposite to the first surface; at least one chip mounted on the first surface of the substrate and electrically connected to the substrate; a heat dissipating structure comprising a first heat sink and a plurality of second heat sinks, wherein the first heat sink has at least one first positioning portion, and each of the second heat sinks has at least one second positioning portion and at least one hollow portion, and wherein the second heat sinks are mounted on the first surface of the substrate and stacked on one another by the second positioning portions thereof, and the first positioning portion of the first heat sink is mounted on the second positioning portion of the uppermost one of the second heat sinks, allowing the chip to be accommodated in a space defined by the first heat sink, the hollow portions of the second heat sinks and the substrate; and a plurality of solder balls mounted on the second surface of the substrate.
