Methods to control the environment and exposure apparatus

摘要

An exposure apparatus includes an exposure system which transfers a pattern of a mask onto a substrate; a chamber in which the exposure system is housed; an air-conditioner which is associated with the chamber and which air-conditions the chamber; and a noise eliminating device which is arranged between the exposure system and the air-conditioner and which eliminates at least a portion of the noise components near a resonant frequency of the exposure system from noise that is generated in the air-conditioner.
