Title:
EXPOSURE SYSTEM, MASK FOR EXPOSURE, EXPOSURE METHOD, DISPLAY, AND ELECTRONIC PARTS
Document Type and Number:
Japanese Patent JP2003162065
Kind Code:
A
Abstract:

To diminish defects in a pattern of a photosensitive material due to dust etc.

After first exposure, the overlap position of the mask pattern of a mask 201 for exposure and a substrate 300 to be exposed in plane view is varied by a prescribed extent in such a way that the mask pattern of the mask 201 overlaps part of a region exposed by the first exposure and exposure is carried out again. For example, when a dry film resist 60 is negative, the pattern of the light transmissive region 201a of the mask 201 corresponds to only part of a (designed) prescribed pattern of the dry film resist 60 to be left after exposure and development.
