Patent ID: 8493173

Claim:
A method of forming a buried resistor within a cavity for use in electronic packages, the steps comprising: a) providing a first glass impregnated dielectric layer having an upper surface and a first lower surface; b) forming a clearance hole in said first glass impregnated dielectric layer; c) providing a second glass impregnated dielectric layer having an upper copper coated surface and a second lower surface; d) removing a portion of said upper copper coated surface of said second dielectric layer, creating a resistor core on said upper copper coated surface; e) disposing said first dielectric layer on said upper copper coated surface of said second dielectric layer; and f) fusion bonding all of said layers together, forming a first subassembly, wherein said clearance hole in said first layer of said dielectric layer surrounds said resistor core on said upper copper coated surface.
