  • Patent number: 11784160
    Abstract: An integrated circuit package substrate (ICPS) system includes a die including a first array of connectors and a substrate including a second array of connectors that is configured to be thermocompression bonded to the first array of connectors at a bonding temperature that is above a solder melting temperature. The first die is bonded to the substrate such that the first die is asymmetric with respect to a substrate center, and the second array of connectors is adjusted, at an alignment temperature that is below the solder melting temperature, for thermal expansion to the bonding temperature with respect to a reference point that is not a first die center.

  • Patent number: 11545444
    Abstract: A lidded chip package apparatus has reduced latent thermal stress in an under-chip high-CTE layer of the chip package because the lid of the package was adhered to a substrate of the package and cured during a same thermal excursion as when underfill was dispensed and cured under a chip of the package, and the chip package was cooled from the combined underfill and lidding process to room temperature with the lid adhered to the chip and the substrate, thereby reducing latent thermal stress in the under-chip high-CTE layer of the chip package.

  • Patent number: 11302205
    Abstract: A computer-implemented method, a computer program product, and an incremental learning system are provided for language learning and speech enhancement. The method includes transforming acoustic utterances uttered by an individual into textual representations thereof, by a voice-to-language processor configured to perform speech recognition. The method further includes accelerating speech development in the individual, by an incremental learning system that includes the voice-to-language processor and that processes the acoustic utterances using natural language processing and analytics to determine and incrementally provide new material to the individual for learning. Responsive to the individual being a baby, the voice-to-language processor discretizes baby babbling to consonants, letters, and words.

  • Patent number: 11239183
    Abstract: A multi-chip module (MCM) package includes an organic laminate substrate; first and second semiconductor device chips that are mounted to a top side of the substrate and that define a chip gap region between opposing edges of the chips; and a stiffener that is embedded in the bottom side of the substrate. The stiffener extends across a stiffening region, which underlies the chip gap region, and does not protrude beyond a bottom side metallization of the substrate.

  • Patent number: 11210968
    Abstract: A computer system interacts with a user with a behavioral state. An activity performed by an entity with a behavioral state is determined. A virtual character corresponding to the entity and performing the determined activity of the entity is generated and displayed. A mental state of the entity responsive to the virtual character is detected. In response to detection of a positive mental state of the entity, one or more natural language terms are provided to the entity corresponding to the activity performed by the virtual character. Embodiments of the present invention further include a method and program product for interacting with a user with a behavioral state in substantially the same manner described above.

  • Patent number: 10985129
    Abstract: Multiple integrated circuit (IC) devices are connected to a top side metallization surface of a multi IC device carrier. The carrier includes resin based substrate layers and associated wiring line layers. To reduce stain of the resin layers, especially in region(s) within the carrier between the IC devices, a stiffener or stiffeners are applied to the back side metallization (BSM) surface of the IC device carrier. The stiffener(s) reduce the amount of curvature of the IC device carrier and reduce the strain seen by the resin layer(s), thereby mitigating the risk for cracks forming and expanding within the resin layers.
