Abstract:
1. A pattern data converting method for generating pattern data using design data representing plural rectangular regions, the method comprising: reconstructing the design data into a column region penetrating through adjacent ones of the rectangular regions in a column direction by a region operation for matching the adjacent ones of the rectangular regions with each other in length; segmenting the column region into apparatus strips; and extracting unit data of the design data for each of the apparatus strips capable of being processed in a time, reconstructing the design data including: defining a rectangular region start code having first and fourth vertex coordinates (X collating the rectangular region start code and the rectangular region end code of each of the rectangular regions with the Y coordinate of first to fourth vertexes of the other of the rectangular regions, dividing the rectangular regions at the Y coordinate of the other of the rectangular regions, and subjecting the rectangular region start code and rectangular region end code having the same Y coordinate to an operation, to obtain the column region.
