Abstract:
1. A method for contacting a plurality of contact areas with a corresponding array of probe tips, wherein the plurality of contact areas is arranged in at least one row on a surface of a semiconductor substrate, wherein the plurality of contact areas and the array of probe tips are positioned relative to one another with a reciprocating device such that the plurality of contact areas and the array of probe tips are opposed to one another and separated by a separation distance in a vertical direction, the method comprising: contacting the plurality of contact areas with corresponding probe tips of the array of probe tips by moving the plurality of contact areas and the array of probe tips toward one another with a vertical feeding motion of the reciprocating device; and observing a contact zone between a probe tip of the array of probe tips and a corresponding contact area of the plurality of contact areas with an observation unit during the contacting, wherein the observing includes:
