    Abstract: A method for exposing a wafer according to pattern data using a charged particle lithography machine generating a plurality of charged particle beamlets for exposing the wafer. The method comprises providing the pattern data in a vector format, rendering the vector pattern data to generate multi-level pattern data, dithering the multi-level pattern data to generate two-level pattern data, supplying the two-level pattern data to the charged particle lithography machine, and switching on and off the beamlets generated by the charged particle lithography machine on the basis of the two-level pattern data, wherein the pattern data is adjusted on the basis of corrective data.

    Abstract: The invention relates to a method of exposing a target by means of a plurality of beamlets. First, a plurality of beamlets is provided. The beamlets are arranged in an array. Furthermore, a target to be exposed is provided. Subsequently, relative movement in a first direction between the plurality of beamlets and the target is created. Finally, the plurality of beamlets is moved in a second direction, such that each beamlet exposes a plurality of scan lines on the target. The relative movement in the first direction and the movement of the plurality of beamlets in the second direction are such that the distance between adjacent scan lines exposed by the plurality of beamlets is smaller than a projection pitch Pproj,X in the first direction between beamlets of the plurality of beamlets in the array.
