Abstract:
It is an object of this invention to prevent a deposited film from adhering to an exhaust chamber so as to suppress the generation of particles. A sputtering apparatus (1) includes a shutter accommodation unit (23) which is detachably placed in an exhaust chamber (8) and accommodates a shutter (19) in a retracted state, and shield members (40a, 40b) which at least partially cover the exhaust port of the exhaust chamber (8), and are at least partially formed around an opening portion of the shutter accommodation unit (23).
