To provide a three-dimensional printing device that irradiates approximately the same ranges on the surface of a powder layer simultaneously with a plurality of electron beams having different beam shapes. An electron beam column 200 of the three-dimensional printing device 100 includes a plurality of electron sources 20 including electron sources having anisotropically-shaped beam generating units, and beam shape deforming elements 30 that deform the beam shapes of electron beams output from the electron sources 20 on a surface 63 of a powder layer 62. A deflector 50 included in the electron beam column 200 deflects an electron beam output from each of the plurality of electron sources 20 by a distance larger than the beam space between electron beams before passing through the deflector 50.

In one embodiment, a charged particle beam writing device writes sequentially patterns to a plurality of deflection positions on a target object by deflecting a charged particle beam by a deflector. The device includes a storage storing relation information indicating a relationship between a time elapsed since a start of deflection by the deflector and an amount of position shift in a shot position to which the charged particle beam is shot, a shot position corrector obtaining a first amount of position shift corresponding to an n-th (where n is an integer greater than or equal to 2) deflection position in sequential pattern writing and a second amount of position shift corresponding to an n−1-th deflection position by using by using a settling time and a shot time of the deflector and the relation information, obtaining an amount of position correction by adding up the first amount of position shift and the second amount of position shift, and correcting a shot position, and a writer emitting the charged particle beam to the n-th deflection position by using the shot data for which the shot position has been corrected, and writing a pattern.

The present application discloses methods, systems and devices for using charged particle beam tools to inspect and perform lithography on a substrate using a combination of vectoring to move a beam to features to be imaged, and raster scanning to obtain an image of the feature(s). The inventors have discovered that it is highly advantageous to use an extra step, a fast raster scan to image the substrate at a lower resolution, to determine which features receive priority for inspection; this extra step can reduce total inspection time, enhance inspection results, and improve beam alignment and manufacturing yield. Using multiple beam-producing columns, with multiple control computers local to the columns, provides various synergies. Preferably, miniature, non-magnetic, electrostatically-driven columns are used.
