  • Patent number: 9524958
    Abstract: A semiconductor device includes a carrier with an interface layer applied over the carrier. The interface layer can include non-conductive paste or non-conductive film. A plurality of semiconductor die is mounted to the carrier and interface layer by pressing the semiconductor die to the carrier and interface layer for one second or less, and simultaneously thermal compression bonding multiple semiconductor die to the carrier and interface layer for 5-10 seconds. By pressing the semiconductor die to the interface layer for a short period of time and then simultaneously thermal compression bonding multiple semiconductor die to the interface layer for a second longer period of time, the overall throughput of die bonding increases to process more die per unit of time. An encapsulant is deposited over the semiconductor die. The carrier is removed and interconnect structure is formed over the semiconductor die and encapsulant.

  • Patent number: 8786076
    Abstract: A semiconductor device includes a substrate with conductive traces. A semiconductor die is mounted with an active surface oriented toward the substrate. An underfill material is deposited between the semiconductor die and substrate. A recess is formed in an interior portion of the semiconductor die that extends from a back surface of the semiconductor die opposite the active surface partially through the semiconductor die such that a peripheral portion of the back surface of the semiconductor die is offset with respect to a depth of the recess. A thermal interface material (TIM) is deposited over the semiconductor die and into the recess such that the TIM in the recess is laterally supported by the peripheral portion of the semiconductor die to reduce flow of the TIM away from the semiconductor die. A heat spreader including protrusions is mounted over the semiconductor die and contacts the TIM.
