The SUSS PA 200 is a semi-automatic wafer prober used for precision semiconductor wafer testing and electrical measurement. The SUSS PA 200 is manufactured in the United States, operates at 400 VA, 110 V, and 60 Hz, and has dimensions of 54 x 32 x 32 inches with a weight of approximately 163.29 kg.[1][2]

A wafer prober holds a semiconductor wafer on a chuck and uses a set of probe needles or a probe card to make temporary electrical contact with individual devices or test structures. The system typically includes a microscope for alignment and a motorized stage for precise positioning. Semi-automatic operation means the operator loads the wafer and initiates the probing sequence, while the machine automates stepping between sites and contact making.
Typical applications include parametric testing, device characterization, and reliability testing of integrated circuits, MEMS, and optoelectronic devices. The prober is also used in research and development environments for process development, failure analysis, and wafer-level testing of novel device structures.
