Abstract
Abstract A pad printer is used to apply multiple patterned layers of alternating materials to form capacitors and resistors within or on ceramic packages. Fast drying resistive, conductive and dielectric inks are used to form very thin (from about 5 to 20 micron) patterned layers for integrated resistors and capacitors. The integrated capacitors may be interconnected in various configuration by patterning clearance holes into the conductive layers which allows the pass-through of electrical connections.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
128 words
An integrated capacitor on a substrate comprising: a patterned thin conductive layer having a first clearance hole; another patterned thin conductive layer having a second clearance hole; a patterned thin dielectric layer positioned between said patterned thin conductive layers; a first through-hole in said substrate through said first clearance hole and said patterned thin layers; a second through-hole in said substrate through said second clearance hole and said patterned thin layers; a conductive material filling said through-holes forming connectors for said integrated capacitor on said substrate; and, another conductive material in said substrate forming connections with the conductive filled through-holes for electrically connecting other components to said integrated capacitor, wherein said another conductive material is printed to said substrate in a shape different than the conductive filled through-holes.
Claim 2
Dependent Claim
128 words
An integrated capacitor on a substrate comprising: a patterned thin conductive layer having a first clearance hole; another patterned thin conductive layer having a second clearance hole; a patterned thin dielectric layer positioned between said patterned thin conductive layers; a first through-hole in said substrate through said first clearance hole and said patterned thin layers; a second through-hole in said substrate through said second clearance hole and said patterned thin layers; a conductive material filling said through-holes forming connectors for said integrated capacitor on said substrate; and, another conductive material in said substrate forming connections with the conductive filled through-holes for electrically connecting other components to said integrated capacitor, wherein said another conductive material is printed to said substrate in a shape different than the conductive filled through-holes.
Claim 3
Dependent Claim
18 words
