发明名称 Charged particle beam exposure method of character projection system, charged particle beam exposure device of character projection system, program for use in charged particle beam exposure device, and manufacturing method of semiconductor device
摘要 A charged particle beam exposure method is disclosed, which includes preparing an aperture mask having character apertures, correcting dimensions of designed patterns in design data in consideration of at least one of factors such as a forward scattering distance of a charged particle, a rearward scattering distance of the charged particle, a blurring of a beam of the charged particle, a dimension conversion difference of the designed patterns due to a denseness/coarseness difference of the designed patterns caused when the underlayer is processed while using the resist as a mask, and the like, allocating at least a part of a specified character aperture of the plurality of character apertures of the aperture mask to the corrected designed patterns to produce writing data, and exposing the resist to the beams of the charged particle passed through the at least a part of the specified character aperture based on the writing data.
