    摘要: A method of making a circuitized substrate which includes at least one and possibly several capacitors as part thereof. In one embodiment, the substrate is produced by forming a layer of capacitive dielectric material on a dielectric layer and thereafter forming channels with the capacitive material, e.g., using a laser. The channels are then filled with conductive material, e.g., copper, using selected deposition techniques, e.g., sputtering, electro-less plating and electroplating. A second dielectric layer is then formed atop the capacitor and a capacitor “core” results. This “core” may then be combined with other dielectric and conductive layers to form a larger, multilayered PCB or chip carrier. In an alternative approach, the capacitive dielectric material may be photo-imageable, with the channels being formed using conventional exposure and development processing known in the art.

    摘要: A capacitive substrate and method of making same in which first and second glass layers are used. A first conductor is formed on a first of the glass layers and a capacitive dielectric material is positioned over the conductor. The second conductor is then positioned on the capacitive dielectric and the second glass layer positioned over the second conductor. Conductive thru-holes are formed to couple to the first and second conductors, respectively, such that the conductors and capacitive dielectric material form a capacitor when the capacitive substrate is in operation.

    摘要: Methods of forming embedded, multilayer capacitors in printed circuit boards wherein copper or other electrically conductive channels are formed on a dielectric substrate. The channels may be preformed using etching or deposition techniques. A photoimageable dielectric is an upper surface of the laminate. Exposing and etching the photoimageable dielectric exposes the space between the copper traces. These spaces are then filled with a capacitor material. Finally, copper is either laminated or deposited atop the structure. This upper copper layer is then etched to provide electrical interconnections to the capacitor elements. Traces may be formed to a height to meet a plane defining the upper surface of the dielectric substrate or thin traces may be formed on the remaining dielectric surface and a secondary copper plating process is utilized to raise the height of the traces.
