Abstract:
To provide a prober and a probe contact method capable of enhancing the reliability of electrical contact between electrode pads on a wafer and probes. A prober includes a wafer chuck, a probe card, a ring-shaped seal member provided on the wafer chuck, a Z-axis moving/rotating unit which lifts up and down the wafer chuck detachably fixed to a wafer chuck fixing part, a decompressor which depressurize an internal space formed by the probe card, the wafer chuck and the ring-shaped seal member, a lifting controller which controls the Z-axis moving/rotating unit to bring probes into contact with electrode pads in an overdrive condition, and a depressurization controller which controls the decompressor such that the wafer chuck is drawn to the probe card by depressurization of the internal space.

Claim (Index 19):
The prober according to  claim 17 , wherein\n at least three guides are provided at positions different from each other in the direction orthogonal to the direction of the movement of the wafer chuck.
