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 20):
The prober according to  claim 17 , further comprising\n a shutter provided separately from the seal member, and capable of switching a communication state between the internal space and an outer space, wherein\n the shutter connects the internal space with the outer space when the wafer chuck is moved toward the probe card by the mechanical lift, and \n the shutter shuts off connection between the internal space and the outer space when the decompressor depressurizes the internal space.
