Patent ID: 7781870

Claim:
A semiconductor apparatus comprising: a semiconductor substrate, the substrate including a plurality of devices, some of which are electrically connected together, some of which are ESD protection devices, and some of which are filtering devices; a plurality of layers disposed over the semiconductor substrate, at least one of the layers being an insulating layer and at least another of the layers being a conducting aluminum layer, the conducting aluminum layer including aluminum wiring that electrically interconnects at least some of the plurality of devices, a plurality of internal wire bond pads and a plurality of external wire bond pads; and a copper redistribution line disposed within an insulating redistribution layer, the redistribution layer disposed over the plurality of layers, the copper redistribution line interconnecting at least some of the internal wire bond pads and further including at least one copper inductor, wherein vertical portions of the insulating distribution layer and corresponding vertical portions of the insulating layer are removed in order to expose the plurality of external wire bond pads yet maintain the copper redistribution line and the copper inductor covered.
