Patent ID: 7592611

Claim:
A creation method of charged particle beam writing data for writing a pattern using a charged particle beam based on design data of circuits, comprising: creating, based on the design data, a location data file including location data, as part of the writing data, the location data being defined for locating one of a plurality of pattern data including one or more elementary patterns in each block area of a plurality of block areas, the plurality of block areas being made by virtually dividing a writing area; creating, based on the design data, a pattern data file including pattern data including the one or more elementary patterns, as part of the writing data; and creating, based on the design data, a link file including link data for linking each of the location data and each of the pattern data, as part of the writing data, wherein the location data file, the pattern data file, and the link file are different from each other and are output as the writing data, and the pattern data is referred to from the location data through the link data.
