    摘要: A lithographic projection apparatus is disclosed where at least part of a space between a projection system of the apparatus and a substrate is filled with a liquid by a liquid supply system. The projection system is separated into two separate physical parts. With substantially no direct connection between the two parts of the projection system, vibrations induced in a first of the two parts by coupling of forces through the liquid filling the space when the substrate moves relative to the liquid supply system affects substantially only the first part of the projection system and not the other second part.

    摘要: In optical maskless lithography, scanning of a single substrate is typically much slower than in conventional lithography. Solutions are described for the adoption of immersion lithography techniques into optical maskless lithography and in particular provides one or more solutions to reduce the amount of time which the immersion liquid is in contact with any given part of the top surface of the substrate during imaging.
