Abstract:
An embedded electrical circuitry structure comprising in order:an epoxy dielectric layer; a first circuitized layer of electrically conductive material; a patterned layer of electrically resistive material having patches of resistive material in contact with the first circuitized layer of conductive material such that resistor electrical pathways are formed through the patches of the resistive material; a layer of embeddable dielectric material having a thickness greater than that of the layer of resistive material such that the patches of resistive material are embedded in the embeddable dielectric material; and a second circuitized layer of electrically conductive material; wherein capacitor electrical pathways are defined between the first and second circuitized layers of electrically conductive material through the layer of embeddable dielectric material.
