    Abstract: A wafer probing system includes a probe card assembly having a plurality of individual probe structures configured make contact with a semiconductor wafer mounted on a motor driven wafer chuck, with each probe structure configured with a pressure sensing unit integrated therewith; and a controller configured to drive the probe card assembly with one or more piezoelectric driver units response to feedback from the pressure sensing units of the individual probe structures.
