Zusammenfassung:A microelectronic package may be fabricated with at least one compliant external bond pad having at least one integrated spring structure for mitigating the effects of warpage of the microelectronic package during attachment to an external substrate. An embodiment for the microelectronic package may include a microelectronic package substrate having a first surface and an opposing second surface, wherein the microelectronic package substrate includes a void defined therein that extends into the microelectronic package substrate from the second surface thereof, and a compliant bond pad suspended over the void, wherein the compliant bond pad includes a land portion and at least one spring portion, and wherein the at least one spring portion extends from the compliant bond pad land portion to an anchor structure on the microelectronic package substrate second surface.
