Patent ID: 7508352

Claim:
A method for fabricating an embedded assembly, the method comprising: providing an organic substrate ( 102 ); providing a first metal layer ( 206 ) existing on top of the organic substrate; embedding at least one movable element ( 104 ) on the organic substrate, wherein the movable element is present on an etched portion of the first metal layer; and embedding at least one antenna element ( 106 ) on the organic substrate, wherein embedding the at least one movable element comprises: providing a second metal layer ( 208 ) on the bottom of the substrate; providing an adhesion promoting treatment layer on the first and the second metal layers; applying a dielectric layer on the adhesion promoting treatment layer, wherein the dielectric layer is coated over the adhesion promoting treatment layer; and wherein the second metal layer is laminated over the dielectric layer, selectively printing and etching the second metal layer; photo-exposing the dielectric layer and baking the embedded assembly; removing the photo-exposed dielectric layer, wherein the photo-exposed dielectric layer is removed by treating the photo-exposed dielectric layer with a solvent to expose the first metal layer; laminating a resin layer on exposed surfaces of the first metal layer and the second metal layer to provide a third metal layer, wherein the third metal layer is one of the plurality of metal layers; and providing and plating one or more microvias and plated through holes.
