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 17):
A prober comprising:\n a wafer chuck configured to hold a wafer; a probe card provided facing the wafer chuck and including probes at positions corresponding to respective electrode pads on the wafer; a seal member having an annular shape, the seal member provided in the wafer chuck and formed to surround the wafer held by the wafer chuck; a mechanical lift configured to detachably support the wafer chuck and capable of vertically move the wafer chuck, the mechanical lift configured to move the wafer chuck toward the probe card until the probes are brought into contact with the electrode pads; a decompressor configured to depressurize an internal space formed by the probe card, the wafer chuck and the seal member, when the wafer chuck is moved toward the probe card by the mechanical lift; and a guide configured to guide movement of the wafer chuck when the wafer chick is drawn to move toward the probe card by depressurization of the internal space, while regulating the movement of the wafer chuck in a direction orthogonal to a direction of the movement of the wafer chuck.
