Abstract
A semiconductor device has a substrate with a plurality of contact pads. A first insulation layer is formed over the substrate and contact pads. A portion of the first insulating layer is removed to form a toroid-shaped SRO over the contact pads while retaining a central portion of the first insulating layer over the contact pads. The central portion of the first insulating layer can extend above a surface of the first insulating layer outside the first conductive layer. A first conductive layer is formed over the central portion of the first insulating layer and through the SRO in the first insulating layer over the contact pads. The first conductive layer may extend above a surface of the first insulating layer outside the second conductive layer. A semiconductor die is mounted to the substrate with the bumps electrically connected to the first conductive layer.
