  • Patent number: 11177065
    Abstract: Examples herein include thermally conductive pathways for glass substrates such as used by passive on glass devices that may be used to enhance the thermal conductivity of an integrated POG device. By using a thermally conductive material for passivation of the device pathways during manufacturing, the device pathways may be able to conduct heat away from the device. For example, by using a selected poly (p-phenylene benzobisoxazole) (PBO) based material (e.g., poly-p-phenylene-2, 6-benzobisoxazole) instead of conventional polyimide (PI) materials during a Cu pattern passivation process, the overall thermal performance of the device, may be enhanced.

    Abstract: Disclosed are devices and methods for on-die electrostatic discharge (ESD) protection in an electronic device. Aspects disclosed include an electronic device including a protected circuit disposed within a die having a first port and a second port. A first inductor is also disposed within the die and is electrically coupled to the first port. A second inductor is also disposed within the die and electrically coupled to the second port. The first inductor and the second inductor are routed in close proximity and are configured so the first inductor is out of phase with the second inductor.

  • Patent number: 10614942
    Abstract: Aspects of the present disclosure provide three-dimensional (3D) through-glass-via (TGV) inductors for use in electronic devices. In some embodiments, a first portion of a 3D TGV inductor may be formed in a first wafer and a second portion of a 3D TGV may be formed in a second wafer. The first portion and second portion may be bonded together in a bonded wafer device thereby forming a larger inductor occupying relatively little wafer space on the first and the second wafers.
