Abstract:
The present disclosure provides a wafer inspection device that can perform accurate inspection. The wafer inspection device includes a probe card having a plurality of contact probes formed to protrude toward a wafer W, a chuck top on which the wafer W is mounted and configured to move toward the probe card, and an aligner configured to adjust inclination of the chuck top relative to the probe card.

Claim (Index 15):
A wafer inspection method of bringing a probe card into contact with a wafer mounted on a chuck top, in a wafer inspection device including a plurality of tester rows composed of a plurality of testers that is horizontally arranged and a conveying stage provided for each of the plurality of tester rows, each of the plurality of testers being provided with the probe card having a plurality of contact terminals formed to protrude toward the wafer, and the conveying stage being provided with an aligner and the chuck top mounted on the aligner, the method comprising:\n an inclination checking step of checking a degree of inclination of the chuck top and a degree of inclination of the probe card, an inclination adjusting step of adjusting the inclination of the chuck top relative to the probe card; and a moving step of moving the chuck top with the wafer mounted thereon toward the probe card; and disposing a first camera for each of the plurality of tester rows, the first camera being configured to move along a respective tester row of the plurality of tester rows, wherein the inclination checking step includes: allowing the first camera to check the degree of inclination of the chuck top; and allowing a second camera disposed in the aligner to check the degree of inclination of the probe card.
