1. A semiconductor package comprising:

  • a substrate;

    a first chip stack structure and a second chip stack structure that are disposed over the substrate and are separate from each other;

    an optical communication part including a first optical transceiver electrically coupled to the first chip stack structure and a second optical transceiver electrically coupled to the second chip stack structure, wherein the first and second optical transceivers are disposed to be faced with each other in a cavity which is formed in the substrate, and provides an optical signal path between the first and second chip stack structures; and

    radiation holes disposed at a separation portion of the substrate, wherein the radiation holes are formed to pass through the separation portion so as to spread out heat that is generated from the first and second optical transceivers, and the separation portion of the substrate is disposed over the cavity and between the first and second chip stack structures.
