Patent ID: 7589416

Claim:
A substrate, comprising: a first conductive member, comprising a plurality of conductive portions electrically insulated from each other by an insulating groove; a second conductive member; and a first insulating member, sandwiched between said first conductive member and said second conductive member, having an opening formed therethrough through said first conductive member to a side of said second conductive member, the side of said second conductive member having electroplating directly thereon with a thickness greater than a depth of said opening and with a width sufficient to completely fill said opening, the side of said second conductive member and all sidewalls of said opening being completely free of non-electrolytic chemical plating such that the electroplating directly contacts the side of said second conductive member and all sidewalls of said opening; wherein the plurality of conductive portions have electroplating directly thereon electrically connecting the plurality of conductive portions to the electroplating on the side of said second conductive member, the electroplating on the plurality of conductive portions filling the groove and having a substantially uniform thickness above the insulating member and the opening.
