Abstract:
LITHOGRAPHIC APPARATUS AND DEVICE MANUFACTURING METHOD USING MULTIPLE EXPOSURES AND MULTIPLE EXPOSURE TYPES A lithographic apparatus and method in which a relatively high resolution exposure, for example of a repeating pattern, is trimmed using a relatively low resolution exposure. According, a compromise between provision of a high resolution pattern and flexibility in the pattern to be formed is provided. Figure 14b

Abstract:
225A lithographic projection apparatus is disclosed for use with an immersion liquid positioned between the final element of the projection system and the substrate W. Several methods are disclosed for protecting components of the projection system, substrate table anda liquid confinement system. These include providing a protective coating on the final10 element 20 of the projection system as well as providing sacrificial bodies upstream of the components. A two component final optical element of CaF2 is also disclosed.[Fig No. 61115
Abstract:
An array of individually controllable elements, comprising a plurality of control areas (20) consisting of a plurality of rows (31,32,33,34) of reflectors. Alternate rows (31,33) of reflectors are actuated in a common manner such that the control areas function as a grating to provide a control element that can be used as a diffractive optical element.
