Patent ID: 7589542

Claim:
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, 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 is configured to contact the pivot; and wherein a ratio between the first portion of displacement energy and the second portion of displacement energy is in the range from about 15:85 to 85:15.
