摘要

A reflecting device that enables to prevent infiltration of particles into a processing chamber. The reflecting device is disposed in a communicating pipe. The communicating pipe allows the processing chamber of a substrate processing apparatus and an exhaust pump to communicate with each other. The exhaust pump has at least one rotary blade. The reflecting device comprises at least one reflecting surface. The at least one reflecting surface is oriented to the exhausting pump.
