Claim Text:
1. A multilayer electronic support structure comprising at least a first feature layer extending in an X-Y plane and a second feature layer extending in an X-Y plane that is parallel to the first feature layer, said first and second feature layers being separated by a via layer; said feature layers comprising metal features surrounded by a dielectric material comprising a polymer matrix and said via layer comprising metal vias surrounded by the dielectric material wherein at least one non-cylindrical via post in the via layer conductively couples a first feature in the first feature layer with a second feature in the second feature layer, such that the first feature and the second feature are not in alignment in a Z direction perpendicular to the X-Y plane and do not overlap; wherein said at least one non-cylindrical via post is characterized by having a long dimension in the X-Y plane that is at least 3 times as long as a short dimension in the X-Y plane.
