Patent ID: 7372144

Claim:
A high speed electronics interconnection system for interconnecting two or more electronic elements on-chip, off-chip or board-board, said interconnection system comprising: at least one electrical signal plane; at least one ground or power plane; a dielectric system interposed between said ground or power plane and said electrical signal plane(s), such that one side of the at least one electrical signal plane is laid on the dielectric system and the second side of the at least one electrical signal plane is exposed to air or a dielectric material, the dielectric system comprising, at least one dielectric layer having at least one backside slot or trench formed under or over said electrical signal plane(s) within the at least one dielectric layer, wherein the backside slot or trench has a width less or more than the width of the electrical signal plane, and wherein the backside slot or trench is filled with a second dielectric material having a dielectric constant lower than the dielectric constant of the at least one dielectric layer; such that connecting two or more electronic elements on-chip, off-chip or board-board, via the at least one electrical signal plane reduces the microwave loss, thereby increasing the signal carrying capacity of said electrical signal plane(s).
