Patent ID: 7629541

Claim:
An interposer comprising: a substrate including first and second opposing surfaces each having a respective exterior, said substrate including a plurality of dielectric layers and a plurality of conductive layers oriented within said substrate in an alternating manner with respect to said plurality of said dielectric layers; a first plurality of parallel openings formed within said substrate and extending substantially therethrough from said first opposing surface to said second opposing surface, each of said first plurality of openings including walls; a substantially continuous, annular, cylindrical conductive layer formed on said walls of each of said first plurality of openings and extending radially outward therefrom to form a land on at least one of said exteriors; a quantity of hardened dielectric material within each of said first plurality of openings and on said substantially continuous, annular, cylindrical conductive layer formed on said wall of said first plurality of openings; a second plurality of parallel openings, each of said second plurality of openings being formed within said hardened dielectric material within respective ones of said first plurality of openings; and a plurality of rigid conductive pin members, each of said conductive pin members subsequently positioned within a respective one of said existing second plurality of openings, said conductive pin members disposed in respective second plurality of openings formed within said hardened dielectric material and extending substantially from beyond said first opposing surface of said substrate to beyond said second opposing surface of said substrate, each of said substantially continuous, annular, cylindrical conductive layers being a shielding member positioned substantially around a respective one of said conductive pin members at a spaced distance therefrom for providing interference shielding for said respective conductive pin member during the passage of high frequency signals therethrough.
