Patent ID: 7016014

Claim:
A lithographic apparatus, comprising: an illumination system that supplies a beam of radiation; a patterning array that patterns the beam of radiation, the patterning array including a plurality of individually controllable elements that each include, a row of substantially parallel planar reflectors, and an actuator system that moves a position of the reflectors in an actuation direction that is substantially perpendicular to the reflectors, wherein the actuator system moves a first group of one or more reflectors in the actuation direction to a respective one of a first plurality of distances from a base of the patterning array, wherein the actuator system moves a second group of one or more reflectors in the actuation direction, independently of the first group, to a respective one of a second plurality of distances from the base; a plurality of focusing elements corresponding to the plurality of individually controllable elements each one of the focusing elements focusing a portion of the beam onto a respective one of the planar reflectors of an associated one of the individually controllable elements in the patterning array; a substrate table that supports a substrate; and a projection system that projects the patterned beam onto a target portion of the substrate.
