Abstract:
PROBLEM TO BE SOLVED: To provide an immersion-type lithography projection apparatus. SOLUTION: In the immersion-type lithography apparatus, an immersion liquid is confined between a final element of a projection system and a substrate. Both of hydrophobic and hydrophilic layers are used on various elements of the apparatus. The use of them helps to prevent air-bubble formation in the immersion liquid, and reduce residues remained on the elements after immersion in the immersion liquid. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a system efficiently and effectively eliminating an energy loss in lithography equipment when a relevant component is locally cooled by the evaporation of a supplied liquid, and defocus and lens aberration are caused by transformation and alteration in immersion lithography for filling a gap between a projection system and a substrate with an immersion liquid in order to increase the number of holes. SOLUTION: A timetable 34 is prepared having information on time at which the evaporation of a supplied liquid 11 is the most likely caused, the position of a substrate W, a speed, an acceleration speed and the like. The evaporation of a local area is prevented by heating at least a portion of the substrate W by using a heater according to the timetable 34 by using a liquid evaporation control device 30 or sending humidified air.

Abstract:
PROBLEM TO BE SOLVED: To provide a lithography projection apparatus and a device manufacturing method, capable of compensating for or improving the effect of a thick pellicle. SOLUTION: The thick pellicle is used to calculate corrections to be applied in exposure so that the thick pellicle is allowed to have a non-flat shape, and the shape compensates for the optical effect of the pellicle. In order for the pellicle to more readily compensate for, to be mounted, in such a manner as to employ a one-dimensional shape under the influence of gravity. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide an immersion lithographic apparatus in which generation of bubbles in the immersion liquid is reduced.SOLUTION: An immersion lithographic projection apparatus has a liquid confinement structure configured to at least partly confine liquid to a space between a projection system and a substrate. The confinement structure having a buffer surface, when in use, is positioned in close proximity to a plane substantially comprising the upper surface of the substrate and of a substrate table holding the substrate, to define a passage having a flow resistance. A recess is provided in the buffer surface. The recess, when in use, is normally full of immersion liquid to enable rapid filling of a gap between the substrate and substrate table as the gap moves under the buffer surface. The recess may be annular or radial and a plurality of recesses may be provided.

Abstract:
PROBLEM TO BE SOLVED: To provide a patterning device for use with a lithographic apparatus and to provide a pellicle to be used therefor. SOLUTION: A method is provided to reduce differences between the way in which reticle holding forces and gravity force act upon the reticle during use and during assembly of the pellicle, and to combine this with a similar reduction concerning pellicle holding forces and gravity force acting upon the pellicle during bonding to the reticle and during quality control of the pellicle. The shape of the pellicle is measured 12 for control in the same orientation of the pellicle with respect to gravity force as during use of the pellicle, and during bonding 16 the pellicle and the reticle are held 17 in the same way and in the same orientation as during control of the pellicle and use of the reticle in a lithographic apparatus.
