Abstract

A maskless lithography system for transferring a pattern onto a surface of a target. At least one beamlet optical unit generates a plurality of beamlets. At least one measuring unit measures properties of each beamlet. At least one control unit generates and delivers pattern data to the beamlet optical unit. The control unit is operationally coupled to the measuring unit for identifying invalid beamlets which have a measured property value outside a predefined range of values for the property. At least one actuator induces a shift of the beamlet optical unit and the target with respect to one another. The actuator is operationally coupled with the control unit. The control unit determines the shift, positioning valid beamlets at the position of the invalid beamlets, thus replacing the invalid beamlets with valid beamlets.
