    摘要: A lithography system includes a source of radiation energy and a zone plate array to focus the radiation energy to create an array of images in order to produce a permanent pattern on a substrate. A phase-shift mask is optically located between the source of radiation energy and the zone plate array. The modulated wavefront produced by the phase-shift mask alters the field diffracted by the zone plate array, and the center lobe of the point-spread function narrows as a result.

    摘要: A system and method are disclosed for providing error correction in an imaging system. The system includes an error determination unit for determining an amount of error associated with a spot at (x,y) in a binary pattern to be imaged, a determination unit for determining the location of a nearest exposed spot at (xi, yi) for each spot at (x,y), and a dose modification unit for modifying an exposure dose at the nearest exposed spot at (xi, yi) for each spot at (x,y).

    摘要: A method is disclosed for forming an array of focusing elements for use in a lithography system. In accordance with an embodiment, the method includes the steps of providing a master element that includes at least one diffractive pattern at a first location with respect to a target surface, illuminating the master element to produce a first diffractive pattern on the target surface at the first location, moving the master element with respect to the target surface to a second location with respect to the target surface, and illuminating the master element to produce a second diffractive pattern on the target surface at the second location.
