Abstract:
A wiring structure comprising:at least two wiring layers including an upper layer residing in an upper wiring plane and a lower layer residing in an lower wiring plane;a void between said upper wiring plane and said lower wiring plane; anda plurality of insulator side support walls attaching to a lower wire in said lower layer and extending substantially upward and attaching to a side of an upper wire in said upper layer and extending along a length of travel of the side surface of said upper wire, the side of said upper wire being substantially perpendicular to a plane of the at least two wiring layers,said plurality of insulator side support walls spanning said void between said upper wiring plane and said lower wiring plane such that a surface of said plurality of insulator side support walls attaching to the side of said upper wire contacts said void, said void extends along the length of travel of said upper wire parallel to the surface of said plurality of insulator side support walls attaching to the side of said upper wire,said plurality of insulator side support walls are further supporting said upper wire over said void over said lower wire and along the length of said upper wire.
