Abstract:
1. A modulation device for use in a maskless lithographic system, wherein said modulation device is a modulation plate comprising an array of modulators, wherein each modulator is adapted for either deflecting a beamlet away from the optical axis of said beamlet or letting a beamlet pass undeflected, said undeflected beamlets passing through the plate to the surface of a target, wherein said plate further comprises light sensitive elements, each light sensitive element in said modulation plate converting a modulated light beam into a signal for controlling one or more modulators of the array, wherein the light sensitive element is integrated in said modulation plate, and wherein the signals are transported from said light sensitive elements to said modulators by electric wires of a chip.
