摘要 |
Various aspects of the invention provide methods of manufacturing probe cards and test systems which may test microelectronic components using such probe cards. In one specific example, a probe card may be manufactured by forming a plurality of blind holes in a substrate, with each hole having a closed bottom spaced from a back of the substrate by a back thickness. An electrically conductive metal may be deposited on the substrate to fill the holes and define an overburden on the substrate. The metal in each hole may define a conductor. At least a portion of the overburden may be removed to electrically isolate each of the conductors from one another. A portion of the substrate including the back thickness is removed to define an array of pins extending outwardly from a remaining thickness of the substrate, with each pin being an exposed length of one of the conductors.
