Patent ID: 7235745

Claim:
A circuitized substrate comprising: a first dielectric layer; first and second electrical conductors spacedly positioned on said first dielectric layer; a quantity of resistor material positioned on said first dielectric layer in contact with said first and second electrical conductors, said quantity of resistor material including a polymer resin and a quantity of non-fired nano-powders including a mixture of at least one metal component and at least one ferroelectric ceramic component, said nano-powders having a particle size within the range of from about 0.01 micron to about 0.9 micron and a surface area within the range of from about 2 to about 20 square meters per gram, said particles of said metal component including a coating of said polymer resin thereon such that said metal particles do not form a single continuous conductive path through said resistor material; and a second dielectric layer positioned over said first and second electrical conductors and said quantity of resistor material such that said quantity of resistor material comprises an internal resistor within said substrate.
