Abstract:
A method for writing a master image on a substrate includes dividing the master image into a matrix of frames, each frame including an array of pixels defining a respective frame image in a respective frame position within the master image. An electron beam is scanned in a raster pattern over the substrate, while shaping the electron beam responsively to the respective frame image of each of the frames as the electron beam is scanned over the respective frame position, so that in each frame, the electron beam simultaneously writes a multiplicity of the pixels onto the substrate.
Abstract:
A method for scanning a specimen 105 with beams 102 of charged particles of a source group. Thereby, a plurality of target points 402 is scanned with a charged particle beam emitted by a source 106 and the same plurality of target points is scanned with at least one further charged particle beam emitted by at least one further source. Further, the charged particle beams from the source and the at least one further source are emitted on the same target point at different times. Additionally, a multiple charged particle beam source and a data feed system are provided. A source array 104 comprises at least one logical emitting unit 106, wherein patterning information is shifted in a shift circuit 140, and redundancy emitting units 106, wherein individual redundancy emitting units obtain patterning information from the shift register.
