  • Patent number: 11900197
    Abstract: Systems and methods are disclosed for systems-in-packages that have multiple shielding components. In one embodiment, a system-in-package may include a substrate, an integrated circuit package disposed on the substrate, a system-on-a-chip disposed on the substrate, and a molding compound disposed over the integrated circuit package and the system-on-a-chip. The system-in-package may include a first electromagnetic interference shielding component disposed about the molding compound, and a second electromagnetic interference shielding component that at least partially forms an outer surface of the system-in-package. The second electromagnetic interference shielding component may have a patterned structure formed thereon.

  • Patent number: 11775119
    Abstract: Systems, methods, and computer-readable media are disclosed for capacitive touch sensing using system-in-package components. In one embodiment, a device may include a flexible printed circuit, and a first system-in-package disposed on a first side of the flexible printed circuit. The first system-in-package may include a first molding compound, and a first electromagnetic interference shield disposed around an outer surface of the first molding compound. The device may include a first capacitive touch sensor, and a first stiffener disposed on a second side of the flexible printed circuit, where the first stiffener can be formed of a conductive material, and can be electrically coupled to both the flexible printed circuit and the first capacitive touch sensor. The first capacitive touch sensor may be configured to detect a change in capacitance via a change in electric field at the first electromagnetic interference shield.

  • Patent number: 11372506
    Abstract: Systems, methods, and computer-readable media are disclosed for systems-in-packages that are encapsulated, at least partially, by a coating serving as electromagnetic interference (EMI) shielding, thereby isolating and otherwise protecting components in the systems-in-package from interference. The systems-in-packages may include one or more capacitive sensors in communication with a portion of the EMI shielding that serves as a sensing pad. In this manner, the system-in-package may benefit from EMI shielding and capacitive touch sensing capability without the complexity and increased cost of a separate capacitive touch sensor and sensing pad.

  • Patent number: 11226415
    Abstract: Systems, methods, and computer-readable media are disclosed for camera modules having integrated time of flight sensors. In one embodiment, an integrated sensor module may include a substrate, a molding compound disposed on the substrate, and a camera sensor disposed on the substrate. The integrated sensor module may include a vertical-cavity surface-emitting laser assembly (VCSEL) disposed on the molding compound and separated from the substrate by a first distance, and a single photon avalanche photodiode assembly (SPAD) disposed on the molding compound and separated from the substrate by the first distance. The camera sensor may be configured to detect a first portion of light emitted by the VCSEL and reflected from an object, and the SPAD may be configured to detect a second portion of light emitted by the VCSEL and reflected from the object.
