    摘要: An exposure system for manufacturing flat panel displays (FPDs) includes a reticle stage adapted to support a reticle. A substrate stage is adapted to support a substrate. A reflective optical system is adapted to image the reticle onto the substrate. The reflective optical system includes a primary mirror including a first mirror and a second mirror, and a secondary mirror. The reflective optical system has sufficient degrees of freedom for both alignment and correction of third order aberrations when projecting an image of the reticle onto the substrate by reflections off the first mirror, the secondary mirror, and the second mirror.

    摘要: A projection system for a lithographic apparatus having a plurality of mirror imaging systems. In an embodiment, the mirror imaging systems are arranged in two rows with each row being perpendicular to a scanning direction of the projection system. Each mirror imaging systems has an associated imaging field. The mirror imaging systems are arranged in a manner that precludes gaps between adjacent imaging fields in the scanning direction. Each mirror imaging system includes a concave mirror and a convex mirror arranged concentrically with the concave mirror. The concave mirrors have a first mirror portion and a second mirror portion that are independently movable. In one embodiment, each of the mirror imaging systems has an associated phase, and the mirror imaging systems in one row are positioned 180 degrees out of phase with the mirror imaging systems in the other row.

    摘要: A lithographic apparatus comprises an illumination system for supplying a beam of radiation, a patterning arrangement incorporating an array of individually controllable elements for imparting a pattern to the beam cross-section, a substrate table for supporting a substrate, and a projection system incorporating a microlens array for projecting the beam onto a target portion of the substrate. An error compensator is provided for supplying error correction values for compensating for the effect of positional errors in the microlens array, and a grey scale modulator is provided for supplying drive signals to controllable elements of the patterning arrangement in dependence on the error correction values in order to compensate for the effect of positional errors in the microlens array by varying the intensity of some parts of the pattern relative to other parts of the pattern.

    摘要: A lithographic apparatus and method in which an illumination system supplies a projection beam of radiation, a patterning system imparts to the beam a pattern in its cross section, and a projection system projects the patterned beam onto a target portion of a substrate supported on a substrate table. The projection system comprises an array of lenses located at a spacing from the substrate such that each lens in the array focuses a respective part of the patterned beam onto the substrate. A displacement system causes relative displacement between the lens array and the substrate. A particle detector is positioned to detect particles on the substrate which are approaching the lens array as a result of relative displacement between the lens array and the substrate. A free working distance control system is arranged to increase the spacing between the lens array and the substrate in response to detection of a particle by the detector such that the lens array is moved away from the substrate as relative displacement causes the detected particle to pass the lens array. Thus damage to the lens array as a result of for example scratching by particles carried on the substrate surface can be avoided.

    摘要: A lithographic apparatus and method for exposing a substrate. An illumination system supplies a series of beams of radiation that are patterned by an array of individually controllable elements. The patterned beams are projected through arrays of lenses onto target portions of a substrate. Each lens in the arrays directs a respective part of the patterned beam towards the substrate. A displacement system causes relative displacement between the substrate and the beam, such that the beams are scanned across the substrate in a predetermined scanning direction. The projection systems are positioned so that each beam is scanned along a respective one of a series of tracks on the substrate. The tracks overlap so that each track comprises a first portion that is scanned by one beam and at least one second portion that overlaps an adjacent track, and is scanned by two beams. A maximum intensity of a first part of each beam directed towards a first portion of the track can be greater than a maximum intensity of a second part of that beam directed towards a second portion of the track, such that the first and second portions of the track are exposed to radiation of substantially the same maximum intensity. Such overlapping of adjacent beams and modulation of the intensity of the beams can allow the optical footprints of different optical columns to be seamed together to enable exposure of large area substrates in a single scan.
