Patent ID: 7355677

Claim:
A lithographic apparatus, comprising: an illumination system that supplies a beam of radiation; an array of individually controllable elements that pattern the beam; and a projection system that projects the patterned beam onto a target portion of a substrate, wherein the array of individually controllable elements includes a substrate having a plurality of supports on which the individually controllable elements are mounted, wherein the individually controllable elements each comprise, a planar reflector, having a reflective surface substantially located in a reflecting plane, and at least two hinges each having an elongated portion, wherein the hinges are each connected at one end to the planar reflector and at the other end to one of the supports on the substrate; wherein the length of the hinges, between the connections to the planar reflector and the support, is at least one of: (a) half of a smallest dimension of the planar reflector across the reflecting plane, (b) equal to the smallest dimension of the planar reflector across the reflecting plane and (c) twice the smallest dimension of the planar reflector across the reflecting plane.
