Patent ID: 7531416

Claim:
A method of making one or more thick-film capacitors on a ceramic interconnect substrate, comprising: providing a glass-ceramic or ceramic interconnect substrate having interconnect circuitry and power and ground pads; forming a first conductive layer on said interconnect substrate, said first conductive layer being connected to either said power pads or said ground pads of said interconnect substrate; optionally firing said first conductive layer at a temperature of at least about 800° C.; forming a capacitor dielectric over the first conductive layer; forming a second conductive layer over the dielectric, said second conductive layer being connected to either said power pads or said ground pads of said interconnect substrate, said second conductive layer being connected only to the power pads or the ground pads that are not connected to said first conductive layer; and cofiring the first conductive layer, the capacitor dielectric and second conductive layer such that the first conductive layer, the capacitor dielectric, and the second conductive layer at a temperature of at least about 800° C. form a capacitor wherein said cofired capacitor dielectric has a thickness in the range of about 10 to 50 microns.
