Patent ID: 7573281

Claim:
A probe comprising: a z deformed portion that is elastically deformed at least in a vertical direction; and a zθ deformed portion that is serially connected to the z deformed portion, the zθ deformed portion rotating while being elastically deformed at least in the vertical direction; wherein the z deformed portion includes: first and second pairs of parallel springs each having two substantially parallel beams of electrically conductive material formed by curves, straight lines, or a curve and a straight line in which the two beams are fixed at both ends thereof by common undeformable supports, the first and second pairs of parallel springs performing translation movement within a certain range when one support of the first pair of parallel springs is fixed and one support of the second pair of parallel springs is moved; and means for connecting the first and second pairs of parallel springs, the means comprising a member of electrically conductive material; and wherein the one support of the first pair of parallel springs is linked to a probe output terminal of the z deformed portion to be electrically coupled to an inspection circuit, and the one support of the second pair of parallel springs is linked to the zθ deformed portion to be electrically coupled to a pad which is a terminal to be measured.
