Patent ID: 8441808

Claim:
An interposer structure, comprising: a dielectric body having a first surface and a second surface, said first and second surfaces being roughly parallel and on opposite sides of said dielectric body; a via formed in said dielectric body between and communicatively coupling said first and said second surfaces; electrically conductive material disposed within said via to thereby electrically connect regions on said first and second surfaces; a microspring formed at least in part over said dielectric body comprising an anchor portion and a free portion in physical and electrical communication with one another; said free portion having a non-planar profile, in the absence of an external force applied thereto, said free portion being free to move relative to said first surface of said dielectric body; said anchor portion being fixed to said dielectric body and disposed for electrical connection thereto at said second surface; and at least a portion of said microspring between said anchor portion and said free portion being disposed within said dielectric body and in electrical communication with said electrically conductive material disposed within said via so as to provide electrical communication between said region on said first surface and said microspring disposed at said second surface.
