  • Patent number: 11114408
    Abstract: Systems and methods for providing 3D wafer assembly with known-good-dies are provided. An example method compiles an index of dies on a semiconductor wafer and removes the defective dies to provide a wafer with dies that are all operational. Defective dies on multiple wafers may be removed in parallel, and resulting wafers with all good dies stacked in 3D wafer assembly. In an implementation, the spaces left by removed defective dies may be filled at least in part with operational dies or with a fill material. Defective dies may be replaced either before or after wafer-to-wafer assembly to eliminate production of defective stacked devices, or the spaces may be left empty. A bottom device wafer may also have its defective dies removed or replaced, resulting in wafer-to-wafer assembly that provides 3D stacks with no defective dies.

  • Publication number: 20210265331
    Abstract: Direct-bonded optoelectronic interconnects for high-density integrated photonics are provided. A combined electrical and optical interconnect enables direct-bonding of fully-processed optoelectronic dies or wafers to wafers with optoelectronic driver circuitry. The photonic devices may be III-V semiconductor devices. Direct-bonding to silicon or silicon-on-insulator (SOI) wafers enables the integration of photonics with high-density CMOS and other microelectronics packages. Each bonding surface has an optical window to be coupled by direct-bonding. Coplanar electrical contacts lie to the outside, or may circumscribe the respective optical windows and are also direct-bonded across the interface using metal-to-metal direct-bonding, without interfering with the optical windows. Direct hybrid bonding can accomplish both optical and electrical bonding in one overall operation, to mass-produce mLED video displays.
