  • Patent number: 12646160
    Abstract: A bonded assembly may be formed by performing a chip plasma clean process on a semiconductor chip; generating at least one chip infrared image of a cleaned side of the semiconductor chip; measuring an average emissivity of at least one metallic region in the at least one chip infrared image; performing a subsequent processing step selected from a bonding step and an alternative processing step based on the measured average emissivity. The bonding step is performed if the measured average emissivity is less than a predetermined emissivity threshold value. The alternative processing step is performed if the measured average emissivity is greater than the predetermined emissivity threshold value. The alternative processing step may be selected from an additional clean step and an additional inspection step.

  • Publication number: 20250125309
    Abstract: Vertically stacked semiconductor devices and methods of fabrication thereof that include a first device structure bonded to a second device structure via bonding layers having compressible metal bonding structures. The compressible metal bonding structures may be fabricated using an electroless deposition (ED) process, and may be less dense with a greater degree of compressibility than equivalent materials deposited by related processes. Accordingly, mating pairs of metal bonding structures may have a degree of compliance that enables effective metal-to-metal contact during a subsequent bonding process. Recrystallization of the metal material during an annealing process may produce shrinkage of the metal material and the formation of void areas between the metal bonds and the surrounding dielectric layers, thereby reducing stress on the surrounding dielectric-to-dielectric interface.
