摘要:
A liquid supply system for an immersion lithographic projection apparatus is disclosed in which a space is defined between the projection system, a barrier member and a substrate. The barrier member is not sealed such that, during use, immersion liquid is allowed to flow out the space and between the barrier member and the substrate.

A lithographic apparatus is disclosed that has a template holder configured to hold an imprint template, a substrate table arranged to receive a substrate, a radiation output arranged to illuminate a part of the imprint template, and a detector configured to detect radiation scattered from an interface between the imprint template and imprintable material provided on the substrate.
摘要:
A method for manufacturing a working template for use in imprint lithography is disclosed, which in an embodiment, involves contacting a first target region of an imprintable medium on a working template substrate with a master template to form a first imprint in the medium, the imprint defining a part of a working template pattern, separating the master template from the imprinted medium, contacting a second target region of the medium with the master template to form a second imprint in the medium, the second imprint defining a further part of the working template pattern, and separating the master template from the imprinted medium.
摘要:
An imprint lithography apparatus is disclosed that has a template holder configured to hold an imprint template, a substrate table, and an optical encoder, the optical encoder having a radiation output, a first diffraction grating, and a detector, the radiation output arranged to illuminate a second diffraction grating and the detector positioned to detect radiation diffracted by the first and second diffraction gratings to provide an alignment signal.
摘要:
The invention relates to variable focus lenses based on magneto wetting and related devices, wherein two fluids, one of which is magnetically susceptible, are in contact over a meniscus. The shape of the meniscus is controlled by means of an applied magnetic field gradient. The contact angle between the chamber wall and the meniscus is a conserved. Implementation of special shaping to the internal or external walls of the chamber, while conserving the contact angle, results in better lens shape in the variable focus lens and lower levels of lens distortion.

A lithographic apparatus is disclosed that has an imprint template or a template holder configured to hold an imprint template, and a substrate table arranged to receive a substrate, the apparatus further comprising walls which together with the substrate table and the imprint template or the template holder, are configured to form an enclosed space which is substantially sealed from a surrounding area.
摘要:
In a lithographic projection apparatus, a structure surrounds a space between the projection system and a substrate table of the lithographic projection apparatus. Gas is used between the structure and the surface of the substrate to contain liquid in the space.
摘要:
For irradiating a layer (3) a radiation beam (7) is directed and focused to a spot (11) on the layer (3), relative movement of the layer (3) relative to the optical element (59) is caused so that, successively, different portions of the layer (3) are irradiated and an interspace (53) between a surface of the optical element (59) nearest to the layer (3) is maintained. Furthermore, at least a portion of the interspace (53) through which the radiation irradiates the spot (11) on the layer (3) is maintained filled with a liquid (91). By directing a gas flow (71-73) to a surface zone (74) of the layer (3), liquid (91) is reliably prevented from passing that surface zone (74), without causing damage to the layer (3). The liquid (91) is drawn away from the layer (3) in the vicinity of the surface zone (74).
摘要:
For irradiating a layer a radiation beam is directed and focussed to a spot on the layer, relative movement of the layer relative to the optical element is caused so that, successively, different portions of the layer are irradiated and an interspace between a surface of the optical element nearest to the layer is maintained. Furthermore, at least a portion of the interspace through which the radiation irradiates the spot on the layer is maintained filled with a liquid, the liquid being supplied via a supply conduit and flowing out of an outflow opening through a total projected cross-sectional passage area in a plane parallel to the layer. The outflow opening or a plurality of the outflow openings are positioned such that, seen in a direction perpendicular to the layer, the total cross-sectional area has a centre in the portion of the interspace through which the radiation irradiates the spot.
