Claim 8:
9. The system according to claim 7, further comprising a radiation beam modulator configured to modulate the radiation beam according to a predetermined profile over time, the profile comprising a plurality of different intensity levels of the radiation beam, wherein the array of individually controllable elements is configured to impart the modulated radiation beam so as to generate a patterned modulated radiation beam by tilting the individually controllable elements between different positions about a tilting axis; and
a control unit, the control unit configured to determine, based on a required dose of radiation for a portion of the substrate and on the predetermined profile over time, a tilting sequence of an element of the array of controllable elements, so as to expose the portion of the substrate to a selection of the plurality of different intensity levels.
