Abstract
A structure and method for achieving a flip-chip semiconductor device having plated copper inductors (), transformers (), interconnect, and power busing that is electrically superior, lower cost, and provides for higher quality inductors as well as lower losses for on-chip transformers. Providing a solder dam () enables the fabrication of flip-chip solder bumps directly on to inductors and transformers.
