Abstract
A probe card tester for detecting defects occurring as a result of integrated circuit processing of a substrate having a plurality of space to conductors with a contact at each end of each conductor, includes: a probe card tester including a set of parallel resistors for connecting at least one in parallel with each conductor and a set of series resistors for connecting together the ends of the conductors to form a series resistance and a number of probe elements, one corresponding to each end of each conductor, for interconnecting the parallel and series resistors with the conductors for detecting defects bridging the conductors.
