Abstract:
A chip fabricated from a semiconductor material is disclosed, which may include active devices located below a first depth from the chip back side, and a structure to remove heat from the active devices to the chip back side. The structure may include thermally conductive partial vias (TCPVs), which may include a recess with a depth, from the chip back side towards the active devices less than the first depth. Each TCPV may include a barrier layer deposited within the recess and deposited upon the back side of the chip. Each TCPV may also include a thermally conductive layer deposited upon the barrier layer. The structure may also include through-silicon vias (TSVs) electrically connected to active devices, extending from the back side to an active device side of the chip to conductively remove heat from the active devices to the back side of the chip.
