Patent ID: 7429510

Claim:
A method of making a capacitive substrate, said method comprising: providing a first capacitive dielectric layer having first and second opposing sides; providing first and second conductors on said first and second opposing sides of said first capacitive dielectric layer, respectively; positioning first and second layers of photoimageable material on said first and second sides of said first capacitive dielectric layer, respectively, including over said first and second conductors; removing first and second portions of said first and second layers of photoimageable material, respectively, to expose said first and second conductors; screen printing a second capacitive dielectric layer onto said first conductor on said first opposing side of said first capacitive dielectric layer and a third capacitive dielectric layer onto said second conductor on said second opposing side of said first dielectric layer, said second and third capacitive dielectric layers including nano-particles and/or micro-particles therein; providing third and fourth conductors on said second and third capacitive dielectric layers, respectively, providing fifth and sixth conductors on said first and second layers of photoimageable material, respectively, said fifth and sixth conductors being electrically isolated from said third and fourth conductors, respectively; forming a first through hole electrical connection between said first, fourth and fifth conductors and a second through hole electrical connection between said second, third and sixth conductors, said first and third conductors and said second capacitive dielectric layer forming a first capacitor, said first and second conductors and said first capacitive dielectric layer forming a second capacitor and said second and fourth conductors and said third capacitive dielectric layer forming a third capacitor when said capacitive substrate is operational.
