ABSTRACT:
A fault position identification system for a semiconductor device includes: a storage unit storing test data of the semiconductor device; a test result analyzer generating test parameters of the semiconductor device, based on failure information of a failure occurred in the semiconductor device; an emission controller controlling the semiconductor device to perform a circuit operation in which the failure occurs, by transmitting the test data corresponding to the test parameters to the semiconductor device; and an observation apparatus observing light emitted from a fault position and identifying the fault position.
