Abstract
A semiconductor manufacturing system includes a semiconductor processing apparatus. The semiconductor processing apparatus includes a processing chamber configured to perform a semiconductor process on a semiconductor wafer, and a transferring module configured to transfer the semiconductor wafer into and out of the processing chamber. The semiconductor manufacturing system also includes a particle attracting member. The semiconductor manufacturing system also includes a monitoring device configured to control the transferring module to load the particle attracting member into the processing chamber in a cleaning cycle while the semiconductor wafer is not in the processing chamber, and control the transferring module to load the particle attracting member out of the processing chamber after the cleaning cycle. In the cleaning cycle, particles in the processing chamber are attracted to the surface of a coating layer of the particle attracting member due to the potential difference between the coating layer and the particles.
