Abstract
A microelectronic structure includes a conductive pad on a substrate. The conductive pad includes first and second openings extending therethrough. A first conductive via on the conductive pad extends through the first opening in the conductive pad into the substrate. A second conductive via on the conductive pad adjacent the first conductive via extends through the second opening in the conductive pad into the substrate. At least one of the conductive vias may be electrically isolated from the conductive pad. Related devices and fabrication methods are also discussed.
