Figure collective electron beam drawing mask, figure collective electron beam drawing mask creation method, and figure collective electron beam drawing apparatus

摘要

The present invention consists in a method of creating an EB mask for electron beam image drawing, comprising: a step of extracting patterns for forming on an EB mask from design data stored in means for storage; a step of calculating an aperture area of an aperture section requested in an EB mask, using the design data contained in the extracted cell; a step of generating cell data for aperture creation using the value of this aperture area; and a step of forming a basic aperture pattern in an EB mask using this cell data for aperture creation.
