3D semiconductor package interposer with die cavity |
摘要 |
A 3D semiconductor package using an interposer is provided. In an embodiment, an interposer is provided having a first die electrically coupled to a first side of the interposer and a second die electrically coupled to a second side of the interposer. The interposer is electrically coupled to an underlying substrate, such as a packaging substrate, a high-density interconnect, a printed circuit board, or the like. The substrate has a cavity such that the second die is positioned within the cavity. The use of a cavity may allow smaller conductive bumps to be used, thereby allowing a higher number of conductive bumps to be used. A heat sink may be placed within the cavity to aid in the dissipation of the heat from the second die.
