Patent ID: 7307691

Claim:
A direct exposure system that performs a direct exposure process using drawing data for forming a desired exposure pattern on a substrate, comprising: a data mask that is a data object including said drawing data; and a control mask that is a data object including at least one logical layer in which information about exposure conditions applied according to regions on the substrate is specified, wherein the direct exposure system performs a desired direct exposure process using integrated data generated by combining said data mask with said control mask, wherein, when pieces of geometrical information corresponding to regions obtained by dividing a plane of said substrate are defined as windows, pieces of information about the exposure conditions applied to said windows are specified in said layer, wherein said exposure conditions specified in said layer are set by using parameters selected from: a first parameter for relative velocity of said direct exposure system with respect to said substrate; a second parameter for intensity of an exposure light source of said direct exposure system; a third parameter for a focal length of said light source; a fourth parameter for synchronization timing of each exposure engine when said direct exposure system is provided with a plurality of exposure engines; a fifth parameter for adjusting overlapped portions of the regions that can be processed by each exposure engine when said direct exposure system is provided with a plurality of exposure engines; a sixth parameter for lighting time of said light source; and a seventh parameter for operating time of said exposure engines.
