Apparatus and method for maintaining immersion fluid in the gap under the projection lens during wafer exchange in an immersion lithography machine
摘要:
A liquid immersion exposure apparatus in which a substrate is exposed to an exposure beam, includes an optical member through which the substrate is exposed to the exposure beam, a cover member having a surface, a first holding system that detachably holds the cover member, and a second holding system that holds the cover member which is released from the first holding system. The surface of the cover member held by the second holding system is opposite to the optical member.
