Title: Method of exposure using disital image
Inventor: LEE JONG GOO
IPC: G03F7/20
Filed: 2021-03-12
Abstract: In a split exposure method, each divided image obtained by dividing the entire image into regions in a maskless digital photolithography process is sequentially transferred to each divided region on a substrate. The method comprises the steps of: forming a divided image by setting a range to have a certain width inward and outward around a boundary line in a section connected to a pattern region of at least an adjacent divided image in the middle of the boundary line of the pattern region which is a region where light is irradiated within each divided image and processing the divided image so that the amount of light or an optical dose is reduced while moving from the inside to the outside within the range; and exposing the corresponding divided region on the substrate by using the processed divided image. According to the present invention, in the case of split exposure, a relatively accurate level of an optical dose is maintained in the pattern region through an exposure method or an exposure amount change given to each position at a boundary part of a pattern even when an expensive high-precision moving stage is not adopted, and even when setting conditions for the movement of a stage in an exposure device are slightly changed, the occurrence of double exposure and non-exposure regions in the pattern region can be suppressed.
