Claim:
1. A package, comprising: an integrated circuit chip supporting a conductive pillar; a substrate having an embedded landing pad coupled to an embedded metal trace, wherein a surface of the embedded landing pad is co-planar with a surface of the embedded metal trace, and wherein an embedded landing pad width is greater than an embedded metal trace width, and wherein an embedded landing pad length is greater than the embedded landing pad width, and wherein the embedded landing pad and the embedded metal trace have an upper surface co-planar with an upper surface of the substrate, the embedded metal trace having a trapezoid cross section; a joint enhancement feature extending from the embedded landing pad, the joint enhancement feature having an “H” shape, wherein the “H” shape is the only raised feature extending from the embedded landing pad; and a solder joint electrically coupling the conductive pillar to the embedded landing pad.
