Abstract:
1. Probe station for testing semiconductor substrates comprising: a chuck for receiving a semiconductor substrate to be tested, a probe holder plate on which probes for electrical contacting of the semiconductor substrate to be tested are disposed by a probe holder, the probes and probe holder comprising a probe arrangement, at least one positioning system for positioning said semiconductor substrate with respect to the probes, a housing enclosing at least the chuck and the probe arrangement and forming an electromagnetic shielding, said housing being subdivided by the probe holder plate into at least a probe housing and an other housing section, the probe housing completely enclosing the probe arrangement, wherein the probe housing is adapted to be opened independently of the other housing section in such a manner that through an opening of the probe housing a part of the probe arrangement or the entire probe arrangement is optionally accessible and at least one section of a wall of the probe housing bounding the probe holder does not participate in the opening of the probe housing, and a device for signal preparation, said device preprocessing and/or processing a signal from the probes, and being disposed within the housing.
