MANUFACTURING METHOD OF COATING FILM, METHOD FOR MAINTAINING COATING ENVIRONMENT, AND COATING FACILITY

摘要

PROBLEM TO BE SOLVED: To reduce defects caused by adherence of environmental foreign matters compared to conventional coating films and thereby improve the yield.SOLUTION: In a manufacturing method of a coating film, a coating slip is applied to a long film 2 being transferred to manufacture a coating film. A trap film 25A which traps environmental foreign matters is formed in at least a portion of a coating head 25 for applying the coating slip, which excludes a coating object side surface.SELECTED DRAWING: Figure 3
