Patent ID: 8242470

Claim:
A method for transferring a pattern onto the surface of a target using a lithography system comprising: beam generating means for generating a plurality of beamlets, and a modulator plate for individually controllably modulating substantially each beamlet, wherein said modulator plate comprises planar array, each modulator of said array of modulators operationally coupled to a light sensitive elements, wherein light sensitive surfaces of the light sensitive elements are all provided on one surface of said modulator plate at one side of the modulation array, said one surface being substantially parallel to said modulator plate, said method comprising: retrieving pattern data; transforming said pattern data into at least one modulated light beam; optically coupling said at least one modulated light beam to said modulator plate via an optical transmitter for transmitting the at least one modulated light beam, carrying modulation data for modulating said beamlets, to said modulator plate, wherein said modulated light beams are projected from ends of fibers on said light sensitive elements and said optical transmitter comprising a group of optical fibers for transporting the at least one modulated light beam towards a respective light sensitive element of said modulators for converting such coupled light signal into an electrical signal for actuating an operationally coupled beam et modulator, wherein said group of optical fibers is combined together to form an optical fiber array, and wherein said fiber ends of the optical fiber array at the modulation array and the modulation array are lying parallel to each other, wherein said optical fiber array is connected to the modulation plate on said one side of the modulator array and wherein the optical fiber array is arranged for transporting the data from a control unit to a region close to the modulator plate.
