Publication number: 20040044981Abstract: CAD (Computer Aided Design) data which is reticle design data is input to first and second data conversion devices which respectively convert the CAD data to electron beam (EB) write data and inspection data. The EB write data and inspection data output are input to a data verification device to verify whether or not there is a data conversion error.
