A lithographic apparatus and method in which an illumination system supplies a projection beam, 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. The projection system comprises an array of lenses spaced from the substrate such that each lens in the array focuses part of the patterned beam onto the substrate. A displacement system causes displacement between the lens array and the substrate. A particle detector detects particles on the substrate which are approaching the lens array. A free working distance control system increases the spacing between the lens array and the substrate in response to detection of a particle. The lens array is moved away from the substrate as the detected particle passes the lens array. Thus damage to the lens array can be avoided.

Lithographic apparatus and device manufacturing method

Substrate processing apparatus includes a lithographic apparatus which comprises an illumination system for supplying a projection beam of radiation, an array of individually controllable elements serving to impart the projection beam with a pattern in its cross-section, and a projection system for projecting the patterned beam onto a target portion of a substrate. The processing apparatus also includes a substrate supply arranged to output at least one unbroken length of substrate, and a substrate conveying system arranged to convey each outputted unbroken length of substrate from the substrate supply and past the projection system such that the projection system is able to project the patterned beam onto a series of target portions along each unbroken length of substrate. In certain embodiments, long lengths of substrate are supplied from a roll, but alternatively a series of separate sheets can be supplied.

Lithographic apparatus, device manufacturing method, and device manufactured thereby

A method of manufacturing first and second substrates that are coupled together, e.g., an active and passive plate of a flat panel display. The active plate is formed according to a standard pattern and inspected. The passive plate is then formed by modifying the pattern data for the passive plate according to the actual pattern formed on the active plate to ensure that the patterns formed on the active and passive plates correspond closely.
