Patent ID: 7382627

Claim:
A laminate structure comprising a capacitive/resistive device, comprising: a first metal foil; a dielectric disposed over the first metal foil; a second metal foil; a resistive layer having two opposing surfaces and disposed over the second metal foil; wherein one surface of the resistive layer contacts the dielectric layer; a first electrode formed by etching the first metal foil; a second electrode and a conductive trace separately formed by etching the second metal foil; the first electrode, the dielectric layer, and the second electrode forming a capacitor; wherein at least a portion of the opposite surface of the resistive layer contacts both the second electrode and the conductive trace, thereby forming a resistor element; wherein the resistor element contacts the dielectric layer, wherein the dielectric comprises a polymer filled with a high dielectric constant powder phase; wherein the dielectric layer is 8-25 micrometers in thickness with a dielectric constant of between 5 and 40, and wherein the dialectic layer is formed by casting a dielectric slurry comprising the polymer, a solvent, and the high dielectric constant powder phase over the first metal foil, the second metal foil, or over the first metal foil and the second metal foil; and wherein the capacitor and resistor are laminated to, and embedded within, at least two printed wiring board dielectric laminate layers.
