Patent ID: 7652348

Claim:
An apparatus, comprising: an integrated circuit with power regulation circuitry fabricated thereon; a switching node contact in electrical connection with the power regulation circuitry on the integrated circuit; an interconnect dielectric layer formed over the power regulation circuitry and the switching node contact of the integrated circuit; a plurality of magnetic core inductor members formed on the interconnect dielectric layer; a plurality of photoresist spacers positioned between the plurality of magnetic core inductor members; a planarization surface formed over the plurality of magnetic core inductor members; an electrically insulating layer formed over the planarization surface; a plating layer formed over the electrically insulating layer, the plating layer including at least one metal; an inductor coil formed over the plurality of magnetic core inductor members; a photoresist material covering at least portions of the inductor coil; and a layer of non-conductive magnetic paste formed over the inductor coil layer, wherein the electrically insulating layer, the planarization surface and the plating layer are positioned between the plurality of magnetic core inductor members and the inductor coil and wherein the non-conductive paste contains magnetic particles having various sizes ranging from approximately 1 to 10 microns and wherein the fill factor of the magnetic particles is between approximately 80 and 90 percent.
