  • Publication number: 20240113155
    Abstract: A microelectronic device includes a galvanic isolation component having a lower isolation element over a substrate with lower bond pads connected to the lower isolation element, a dielectric plateau over the lower isolation element that does not extend to the lower bond pads, and an upper isolation element and upper bond pads over the dielectric plateau. The upper bond pads are laterally separated from the lower bond pads by an isolation distance. The microelectronic device includes high voltage wire bonds on the upper bond pads that extend upward, within 10 degrees of vertical, for a vertical distance greater than the isolation distance. The microelectronic device further includes low voltage wire bonds on the lower bond pads that have a loop height directly over a perimeter of the substrate that is less than 5 times a wire diameter of the low voltage wire bonds.
