ABSTRACT:
A probing apparatus for use in examination of a chip formed on a wafer, in co-operation with a sheet-like member having probe needles to be contacted to the chip on the wafer, the probing apparatus being arranged so that the positions of the probe needles of the sheet-like member, when it is held by a holder of the probing apparatus, are detected automatically and, in accordance with the detected positions, the sheet-like member is displaced automatically so as to be aligned with the probing apparatus. According to another aspect of the invention, the position of the wafer when it is at a location under the probe needles is detected automatically and, in accordance with the detected position, the wafer is displaced so as to be aligned with the sheet-like member which has been aligned automatically with the probing apparatus. In one preferred form, a TV camera is provided at a position above the probing station, the TV camera being adapted to view the probe needles of the sheet-like member during positioning of it and to view the wafer when it is at a probing station, during positioning of the wafer.
