Patent ID: 8537527

Claim:
A mounting board comprising: a substrate; a plurality of first metal lines formed on the substrate and extending in a first direction, each first metal line having a conductive via portion formed thereon; an interlayer insulating film formed over the via portions and the first metal lines; a plurality of first metal contacts corresponding to the plurality of first metal lines, each first metal contact formed on one of the via portions and on portions of the interlayer insulating film surrounding the via portions; a plurality of second metal lines formed on the interlayer insulating film and extending in a second direction that is perpendicular to the first direction; and a plurality of second metal contacts corresponding to the plurality of second metal lines, each second metal contact formed on the interlayer insulating film and electrically connected to respective ends of the second metal lines, wherein the first metal contacts, the second metal lines, and the second metal contacts are formed from a single coplanar metal layer, wherein the first metal contacts are arranged in zigzags in the second direction, and the second metal contacts are arranged in zigzags in the first direction, and wherein each of the first metal contacts are formed over a plurality of first metal lines in plan view, and each of the second metal contacts are formed over a plurality of second metal lines in plan view.
