Patent ID: 8049110

Claim:
A microelectronic device comprising: a dielectric layer that includes a front surface that defines a front plane and a rear surface that defines a rear plane; a first conductive structure positioned within said dielectric layer and including a first exposed surface positioned in said front plane, said first conductive structure further comprising a first anchor structure positioned rearwardly from said front plane, said first anchor structure defining a cross sectional dimension greater than a cross sectional dimension of said first exposed surface of said first conductive structure, and a back surface of said first anchor structure positioned completely forwardly of said rear plane and a nonconductive material between said back surface of said first anchor structure and said rear plane electrically isolating said first conductive structure from said rear plane of said dielectric layer; and a second conductive structure positioned within said dielectric layer and including a second exposed surface positioned in said front plane, said second conductive structure further comprising a second anchor structure positioned rearwardly from said front plane, said second anchor structure defining a cross sectional dimension greater than a cross sectional dimension of said second exposed surface of said second conductive structure, and said second anchor structure of said second conductive structure electrically exposed on said rear surface of said dielectric layer.
