  • Multilayer high voltage isolation barrier in an integrated circuit
    Patent number: 9035422
    Abstract: A semiconductor package is provided that has a transformer formed within a multilayer dielectric laminate substrate. The transformer has a first inductor coil formed in one or more dielectric laminate layers of the substrate, a second inductor coil formed in one or more dielectric laminate layers of the substrate, and an isolation barrier comprising two or more dielectric laminate layers of the multilayer substrate positioned between the first inductor coil and the second inductor coil. The transformer may be mounted on a lead frame along with one or more integrated circuits and molded into a packaged isolation device.
    Type: Grant
