Zusammenfassung:PURPOSE:To realize a block plotting type charged-particle beam lithographic method capable of plotting a required pattern even when block mask is not prepared. CONSTITUTION:A discrimination circuit 11 reads the library number of pattern data, judges whether or not the number is registered to a register 13. reads a block number corresponding to the library number when the number is registered, and the data are transmitted over a block selector circuit 14. The block selector circuit 14 generates a deflection signal for deflecting the electron beam to a block to be selected. Consequently, the electron beam EB is deflected to the position of the desired block, and the electron beam passing through the block is projected onto a material 2. A deflection signal based on pattern data is transmitted over a positioning deflector 3 at that time, and the electron beam having a specified sectional shape is projected in the fixed position of the material.
