  • Patent number: 9892935
    Abstract: An electronic package includes a carrier, semiconductor chip, a lid, and a lid-ring. The carrier includes a top surface and a bottom surface configured to be electrically connected to a system board. The semiconductor chip is electrically connected to the top surface. The lid is attached to the top surface enclosing semiconductor chip and includes a perimeter recess. The lid-ring is juxtaposed within the perimeter recess. The lid-ring exerts a reverse bending moment upon the lid to limit warpage of the electronic package.

  • Publication number: 20170170030
    Abstract: An electronic package includes a carrier and a semiconductor chip. In a first aspect a lid is attached to the chip and subsequently the gap between the lid and the carrier is filled by a seal band that includes seal band material and a plurality of shim members. In another aspect, an interleaved seal band includes a pattern of a first type of seal band material and a second type of seal band material. In another aspect, the lid includes a plurality of surfaces at different topographies to reduce the thickness of the seal band between the topographic lid and the carrier. In yet another aspect the electronic package further includes a frame concentric with the chip. The lid is attached to the frame with a solder, epoxy or elastomer and placed on the chip with a thermal interface material. The seal band material is dispensed on the chip carrier and the frame is then moved towards the chip carrier allowing a minimum seal band thickness.

  • Patent number: 9673064
    Abstract: A lattice structure is formed in a non-silicon interposer substrate to create large cells that are multiples of through hole pitches to act as islands for dielectric fields. Each unit cell is then filled with a dielectric material. Thereafter, holes (i.e., through holes or blind holes) are created within the dielectric material in the cells. After hole formation, a conductive metal is formed into each of the holes providing an interposer. This method can enable fine pitch processing in organic-based materials, isolates the thermal coefficient of expansion (TCE) stress from metal vias to low TCE carriers and creates a path to high volume, low costs components in panel form.

  • Patent number: 9466538
    Abstract: A method of improving chip-to-chip alignment accuracy for circuitry-including wafer-to-wafer bonding. The method comprises providing separate stages for holding first and second circuitry-including wafers, each stage including a plurality of adjacent thermal actuators arranged in an array integrated with the stage; determining planar distortions of a bonding surface of the first and second circuitry-including wafers; mapping the planar distortions for each wafer based on the relative planar distortions thereon; deducing necessary local thermal expansion measurements for each wafer to compensate for the relative distortions based on the mapping; translating the thermal expansion measurements into a non-uniform wafer temperature profile model and a local heat flux profile model for each wafer; aligning the first and second wafers; and bonding the first and second wafers together.
