Patent ID: 7295885

Claim:
A drawing method for drawing a pattern on a drawing surface comprising: a first converting step in which first vector-graphic data of a drawing-coordinate-system, that represents all information on said pattern, is converted in an exposure drawing apparatus having a plurality of optical modulation elements, to second vector-graphic data of an exposing-coordinate-system that conforms to said exposure drawing apparatus; a second converting step in which said second vector-graphic data is converted to raster-graphic data of the exposing-coordinate-system, to control the exposure by said optical modulation elements; and a multi-exposing step in which said drawing surface is multi-exposed for drawing said pattern, based on said raster-graphic data, wherein, in said second converting step, said second vector-graphic data is put in order and assigned a number according to the coordinate system values of each of said second vector-graphic data, all of said second vector-graphic data is divided into odd-numbered vector-graphic data and even-numbered vector-graphic data based on each said number of said second vector-graphic data, and said second vector-graphic data is converted to said raster-graphic data, by dividing an exposing area which is an exposable area in the exposing-coordinate-system, into exposed zones and un-exposed zones based on said odd-numbered vector-graphic data and said even-numbered vector-graphic data.
