Abstract:
A shielded interconnect bus crossover comprising:a substrate; first, second, and third layers of electrically conductive material overlying and supported by at least a portion of said substrate; an interconnect bus patterned from said first and second layers of electrically conductive material, said interconnect bus including a plurality of interconnect bus lines, a plurality of interconnect bus shield walls, and an interconnect bus shield supported in a spaced relation above said interconnect bus lines by said interconnect bus shield walls; a plurality of base pads patterned from said first layer of electrically conductive material, said base pads being located at locations within the footprint of said interconnect bus along an imaginary line extending transverse to an orientation of said interconnect bus lines, at least one of said base pads being in contact with at least one of said interconnect bus lines; a plurality of support columns patterned from said second layer of electrically conductive material, said support columns overlying said base pads and extending vertically upward through holes formed in said interconnect bus shield; and at least one elevated crossing line patterned from said third layer of electrically conductive material, said elevated crossing line being supported in a spaced relation above said interconnect bus shield by said support columns.
