  • Patent number: 9281228
    Abstract: A semiconductor device has a semiconductor die mounted to a substrate. A recess is formed in a back surface of the semiconductor die to an edge of the semiconductor die with sidewalls on at least two sides of the semiconductor die. The sidewalls are formed by removing a portion of the back surface of the die, or by forming a barrier layer on at least two sides of the die. A channel can be formed in the back surface of the semiconductor die to contain the TIM. A TIM is formed in the recess. A heat spreader is mounted in the recess over the TIM with a down leg portion of the heat spreader thermally connected to the substrate. The sidewalls contain the TIM to maintain uniform coverage of the TIM between the heat spreader and back surface of the semiconductor die.

  • Patent number: 8703535
    Abstract: A method of manufacture of an integrated circuit packaging system includes: providing a package substrate having a warpage-compensation zone with a substrate-interior layer exposed from a top substrate-cover, and the warpage-compensation zone having contiguous exposed portion of the substrate-interior layer over corner portions of the package substrate; connecting an integrated circuit die to the package substrate with an internal interconnect; and forming an encapsulation over the integrated circuit die, with the encapsulation directly on the substrate-interior layer in the warpage-compensation zone.

  • Patent number: 8679900
    Abstract: A method of manufacture of an integrated circuit packaging system includes: providing a substrate; mounting an integrated circuit over the substrate; mounting a lid base over the substrate, the lid base having a base indentation and a hole with the integrated circuit within the hole; and mounting a heat slug over the lid base, the heat slug having a slug non-horizontal side partially within the base indentation.

  • Publication number: 20130049188
    Abstract: A semiconductor device has a semiconductor die mounted to a substrate. The semiconductor die and substrate are disposed within a mold chase with a releasing layer disposed over the semiconductor die. A MUF material is deposited around the semiconductor die, releasing layer, and substrate through an opening in the mold chase. The opening in the mold chase is located in an upper mold support of the mold chase. A recess is formed in the MUF material by removing the releasing layer. A TIM is formed in the recess of the MUF material. The TIM is substantially coplanar with the MUF material. A heat spreader is formed over the TIM material. The heat spreader can be formed within the recess of the MUF material over the TIM. A plurality of bumps is formed over a surface of the substrate opposite the semiconductor die.
