Abstract

The present disclosure provides a system and a method for monitoring semiconductor manufacturing equipment. The system includes a sensor, a circuit, and an analysis unit. The sensor provides a sensor signal. The circuit receives the sensor signal and generates an input signal. The analysis unit includes a signal management platform, receiving the input signal and performing a first data process to generate a first data signal; a diagnosis subsystem, receiving the first data signal from the signal management platform and performing a health status monitoring process to generate a second data signal; and a decision subsystem, performing a determination process to generate a third data signal according to the second data signal from the diagnosis subsystem. The diagnosis subsystem generates a feedback signal according to the third data signal, and the signal management platform transmits the feedback signal to the semiconductor manufacturing equipment.
