Patent ID: 7501843

Claim:
A method of a prober for correcting a movement amount operation correction value in a prober, the prober including: a probe card having a probe; a wafer chuck for holding a wafer on which an electrode is formed; a moving mechanism for moving the wafer chuck; a probe position detection means for detecting a position of the probe of the probe card; a wafer alignment means for detecting a position of the electrode of the wafer held by the wafer chuck; and a movement control section for controlling the moving mechanism, the movement control section comprising a movement amount operation section for calculating an amount of movement by the moving mechanism such that a predetermined position of the electrode is brought into contact with the probe based on the position of the probe detected by the probe position detection means, the position of the electrode detected by the wafer alignment means, and the movement amount operation correction value, the method comprising: with the probe position detection means, detecting the position of the probe of the probe card; with the wafer alignment means, detecting the position of the electrode; bringing the electrode into contact with the probe; with the wafer alignment means, processing an image of a probe trace on the electrode touched by the probe to detect a position of the probe trace; displaying an image of the probe trace and a probe trace mark indicating the detected position of the probe trace on a display device; confirming or correcting the position of the probe trace mark on the image; calculating a shift of the position of the probe trace mark from the predetermined position; and correcting the movement amount operation correction value based on the calculated shift.
