摘要：
A barrier member is provided for use in immersion lithography. The barrier member includes an extractor assembly on a bottom surface which faces the substrate. The extractor assembly includes a plate which splits the space between a liquid removal device and the substrate in two such that a meniscus is formed in an upper channel between the liquid removal device and the plate and a meniscus is formed in a lower channel between the plate and the substrate.
