A maskless lithography system for transferring a pattern onto the surface of a target. At least one beam generator for generating a plurality of beamlets. A plurality of modulators modulate the magnitude of a beamlet, and a control unit controls of the modulators. The control unit generates and delivers pattern data to the modulators for controlling the magnitude of each individual beamlet. The control unit includes at least one data storage for storing the pattern data, at least one readout unit for reading out the data from the data storage, at least one data converter for converting the data that is read out from the data storage into at least one modulated light beam, and at least one optical transmitter for transmitting the at least one modulated light beam to the modulation modulators.

Optical switching in lithography system

The invention relates to a modulator for modulating the magnitude of a beamlet in a multi-beamlet lithography system, said modulator comprising at least one means for influencing the direction of a beamlet, a light sensitive element for receiving light from a modulated light beam and converting said light into a signal, and discretizing means, coupling to said light sensitive element and to at least one of means for influencing, for converting said signal received from said light sensitive element into a discrete signal having discrete values selected from a set of predefined discrete values and providing said discrete signal to said means for influencing.
