WIRE BONDS FOR GALVANIC ISOLATION DEVICE
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.

QFN PIN ROUTING THRU LEAD FRAME ETCHING
A multi-level leadframe including three bonding levels and one exposed level. Each of the three bonding levels and the one exposed level is positioned in a different horizontal plane, with each bonding level providing a bonding site vertically positioned relative to the horizontal plane of the exposed level, with each bonding site coupled to a package lead at the exposed level. Bonding sites located at first and second bonding levels can be located in a common, outer row, along a common, vertical plane, and bonding sites located at a third bonding level can be located in a separate, inner row, along a separate vertical plane.
