摘要： A high density region for a low density circuit. At least a first liquid dielectric layer is deposited on the first surface of a first circuitry layer. The dielectric layer is imaged to create plurality of first recesses. Surfaces of the first recesses are plated electro-lessly with a conductive material to form first conductive structures electrically coupled to, and extending generally perpendicular to, the first circuitry layer. A plating resist is applied. A conductive material is electro-plated to the first conductive structure to substantially fill the first recesses, and the plating resist is removed.
