    Abstract: A method of making a fusion bonded circuit structure. A substrate is provided with a seed layer of a conductive material. A first resist layer is deposited on the seed layer. The first resist layer is processed to create first recesses corresponding to a desired first circuitry layer. The first recesses expose portions of the seed layer of conductive material. The substrate is electroplated to create first conductive traces defined by the first recesses. The first resist layer is removed to reveal the first conductive traces. The substrate is etched to remove exposed portions of the seed layer adjacent the first conductive traces. A portion of the seed layer is interposed between the first conductive traces and the substrate. A first layer of LCP is fusion boned to the first major surface of the substrate to encapsulate the first conductive traces in an LCP material. The first LCP layer can be laser drilled to expose the conductive traces.
