Claim 6:
7. A system for projecting a patterned radiation beam onto a substrate, the system comprising:
an array of individually controllable elements, the array configured to impart a radiation beam so as to generate a patterned radiation beam by tilting the individually controllable elements between different positions about a tilting axis; and
a stage apparatus configured to hold a substrate and configured to scan a substrate across the patterned radiation beam in a scanning direction so as to expose the substrate to the patterned radiation beam,
wherein the tilting axis of the individually controllable elements is substantially perpendicular to the scanning direction, and
wherein a tilt angle variation of a controllable element of the array of individually controllable elements causes substantially only a positional variation in the scanning direction of a portion of the patterned radiation beam that is imparted by the controllable element and that is projected towards the substrate.
