    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.

    摘要: A method of making a circuitized substrate which involves forming a plurality of individual film resistors having approximate resistance values as part of at least one circuit of the substrate, measuring the resistance of a representative (sample) resistor to define its resistance, utilizing these measurements to determine the corresponding precise width of other, remaining film resistors located in a defined proximity relative to the representative resistor such that these remaining film resistors will include a defined resistance value, and then selectively isolating defined portions of the resistive material of these remaining film resistors while simultaneously defining the precise width of the resistive material in order that these film resistors will possess the defined resistance.

    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. In still another embodiment, at least two spaced-apart conductors may be formed within a metal layer deposited on a dielectric layer, these conductors defining a channel there-between. The capacitive dielectric material may then be deposited (e.g., using lamination) within the channels.
