Abstract:
1. An apparatus for providing simultaneous electrical connections from an integrated circuit tester to an array of integrated circuit dice on a wafer, comprising: a plurality of interface modules, each of said interface modules comprising means for making simultaneous electrical connections to said dice; each of said interface modules further comprising a first planar region at a first end and a second planar region which extends said first end to a second end opposite said first end, said interface module comprising a plurality of electrically conductive pads disposed on sold first planar region for providing electrical connections to pads on said dice; and an interconnection link for providing an electrical connection to said tester at said second end and at least one electrical connection extending from at least one of said electrically conductive pads to said interconnection link; and a substrate having a probe surface and a connector surface, said probe surface having a plurality of probe contact tips for making simultaneous electrical contact to electrical contact pads of each of said integrated circuit dice, and a plurality of connections extending through said substrate between each of said plurality of said contact tips and said connector surface for interconnection with said electrically conducting pads; wherein said probe contact tips comprise a stress metal spring.
