Abstract:
1. A probe card for testing a semiconductor device, comprising: a substrate; a hybrid probe connected to the substrate, the probe comprising a base that is connected to the substrate, a torsion element connected to the base, a bending element connected to the torsion element through a union angle, where the union angle comprises an angle in a range from −90 to 90 degrees and a probe tip connected to the bending element; wherein the probe elastically stores displacement energy while the probe tip contacts the device; and wherein the torsion element is adapted to twist such that the torsion element elastically stores a first portion of displacement energy and the bending element is adapted to bend such that the bending element elastically stores a second portion of the displacement energy; a pivot connected to the substrate, wherein a portion of the probe may contact the pivot; and an elevator element adapted to elevate the bending element from the torsional element.
