Abstract
A described example includes: a semiconductor die having bond pads on a device side surface; a passivation layer overlying the device side surface of the semiconductor die with openings in the passivation layer, the passivation layer having a planar surface facing away from the device side surface of the semiconductor die; post connects formed on the bond pads and in the openings in the passivation layer, the post connects having a proximate end on the bond pads and extending from the bond pads to a distal end that lies beneath the planar surface of the passivation layer; solder at the distal ends of the post connects and contacting sidewalls of the openings in the passivation layer; and solder joints formed between the solder at the distal ends of the post connects and a package substrate, the device side surface of the semiconductor die facing the package substrate.
