摘要:
A lithographic projection apparatus is disclosed in which the space between the final element of the projection system and a sensor is filled with a liquid.
摘要:
A lithographic projection apparatus is disclosed in which the space between the final element of the projection system and the substrate is filled with a liquid. An edge seal member 17, 117 at least partly surrounds the substrate W or other object on the substrate table WT to prevent catastrophic liquid loss when edge portions of the substrate or are imaged or illuminated.
摘要:
A lithographic apparatus having means for supplying to a space in the apparatus at least one of one or more perhalogenated C 1 -C 6 alkanes and one or more compounds consisting essentially of one or more nitrogen atoms and one or more atoms selected from hydrogen, oxygen and halogen. The activation of the alkane(s) and compound(s) by application of suitable activating means provides reactive species which are capable of highly selective etching of hydrocarbon species whilst minimising damage to sensitive optical surfaces.
摘要:
A liquid supply system (24) for an immersion lithographic projection apparatus is disclosed in which a space (5) is defined between the projection system (PL), a barrier member (10) and a substrate (W). The barrier member (10) is not sealed such that, during use, immersion liquid is allowed to flow out the space and between the barrier member (10) and the substrate (W).
