Abstract:
A lithography pattern data generation method for generating, from plural design data corresponding to design patterns, lithography pattern data to be drawn correspondingly to said design patterns on a substrate by using an exposure beam of charged particles, comprising:an area dividing step of dividing a predetermined area where said plural design data are arranged, which corresponds to an area where said design patterns are to be formed, into plural partial exposure areas each in the shape of a stripe with a width corresponding to a deflection width of said exposure beam; a data group extracting step of extracting, from said plural design data, design data each falling within any of said plural partial exposure areas as a first design data group, and extracting design data each extending over two or more of said plural partial exposure areas as a second design data group; a first lithography pattern data generating step of generating first lithography pattern data of each of said plural partial exposure areas from said design data belonging to said first design data group; and a second lithography pattern data generating step of generating second lithography pattern data of each of said plural partial exposure areas from said design data belonging to said second design data group.
