摘要
Fault detection apparatuses and methods for detecting a processing or hardware performance fault of a semiconductor production tool have been provided. In an exemplary embodiment, a method for detecting a fault of a semiconductor production tool includes sensing a signal associated with a test component of the production tool during operation of the production tool and converting the signal to an electronic test signal. A prerecorded signature signal corresponding to the test component is provided and the test signal and the prerecorded signature signal are compared.
