Abstract
The present disclosure is directed to systems and methods for improving heat distribution and heat removal efficiency in PoP semiconductor packages. A PoP semiconductor package includes a first semiconductor package that is physically, communicably, and conductively coupled to a stacked second semiconductor package. A thermally conductive member that includes at least one thermally conductive member may be disposed between the first semiconductor package and the second semiconductor package. The thermally conductive member may include: a single thermally conductive element; multiple thermally conductive elements; or a core that includes at least one thermally conductive element. The thermally conductive elements are thermally conductively coupled to an upper surface of the first semiconductor package and to the lower surface of the second semiconductor package to facilitate the transfer of heat from the first semiconductor package to the second semiconductor package.
