Patent ID: 7541265

Claim:
A method of making a circuitized substrate having a capacitor included therein, said method comprising: providing a first organic dielectric layer; forming a first electrical conductor on said first organic dielectric layer; positioning a second dielectric layer on said first organic dielectric layer and said first electrical conductor, said second dielectric layer being in an uncured state; forming an opening within said second dielectric layer to expose said first electrical conductor; filling said opening within said second dielectric layer with a quantity of capacitive dielectric material in paste form, using a screen printing operation having a mesh screen and maintaining the openings of a fine mesh screen, said quantity of capacitive dielectric material being positioned on said first electrical conductor and including a hexahydro-4-methylphthalic anhydride polymer resin and a quantity of nano-powders of ferroelectric ceramic material having a particle size substantially in the range of from about 0.01 microns to about 0.90 microns and a surface area for selected ones of said particles within the range of from about 2.0 to about 20 square meters per gram; and positioning a second electrical conductor substantially on said quantity of capacitive dielectric material on said first electrical conductor, said positioning of said second electrical conductor substantially fully curing both said second dielectric layer and said quantity of capacitive dielectric material in said opening within said second dielectric layer, said first electrical conductor, said quantity of capacitive dielectric material and said second electrical conductor forming a capacitor within said circuitized substrate.
