  • Patent number: 11810892
    Abstract: A method of bonding semiconductor components is described. In one aspect a first component, for example a semiconductor die, is bonded to a second component, for example a semiconductor wafer or another die, by direct metal-metal bonds between metal bumps on one component and corresponding bumps or contact pads on the other component. In addition, a number of solder bumps are provided on one of the components, and corresponding contact areas on the other component, and fast solidified solder connections are established between the solder bumps and the corresponding contact areas, without realizing the metal-metal bonds. The latter metal-metal bonds are established in a heating step performed after the soldering step. This enables a fast bonding process applied to multiple dies bonded on different areas of the wafer and/or stacked one on top of the other, followed by a single heating step for realizing metal-metal bonds between the respective dies and the wafer or between multiple stacked dies.

The first layer of the multilayer coating is a soft electroplated copper to smooth the surface of the base material. The second layer of the multilayer coating is a thin precious metal to facilitate a mechanical coupling between leads of the lead frame and conductive connectors. The third layer of the multilayer coating is the adhesion promotion compound for facilitating a mechanical coupling to an encapsulant around the lead frame.

  • Patent number: 11749577
    Abstract: A multi-chip unit suitable for chip-level packaging may include multiple IC chips that are interconnected through a metal redistribution structure, and that are directly bonded to an integrated heat spreader. Bonding of the integrated heat spreader to the multiple IC chips may be direct so that no thermal interface material (TIM) is needed, resulting in a reduced bond line thickness (BLT) and lower thermal resistance. The integrated heat spreader may further serve as a structural member of the multi-chip unit, allowing a second side of the redistribution structure to be further interconnected to a host by solder interconnects. The redistribution structure may be fabricated on a sacrificial interposer that may facilitate planarizing IC chips of differing thickness prior to bonding the heat spreader. The sacrificial interposer may be removed to expose the RDL for further interconnection to a substrate without the use of through-substrate vias.

  • Patent number: 11749579
    Abstract: An IC package includes a heat-generating device and an electrical device on a surface of a substrate, a mold compound disposed on the electrical device, and a thermal structure disposed on the heat-generating device, without the mold compound, to improve heat dissipation. In an example, the thermal structure includes a thermal interface material (TIM) layer and a heat sink. In the example, the TIM layer extends from the heat-generating device to a height equal to or less than the mold compound and the heat sink includes a planar exterior surface above the heat-generating device and the electrical device. In an example, a first heat sink portion of the heat sink on the heat-generating device may be a different thickness than a second heat sink portion of the heat sink on the electrical device. The thermal structure reduces a thermal resistance between the heat-generating device and the heat sink.
