<p>PURPOSE:To eliminate need of a drying process for simplifying manufacturing, and prevent occurrence of environmental problems or defective products by using UV-ray hardening type resin composite material for material of an etching resistant layer applied to and filled in a recessed hole. CONSTITUTION:A drying process is omitted by using UV-ray hardening type resin for resin composite material to be applied to be an etching resistant layer 12. For example of the etching resistant layer 12 to be applied to and filled in a recessed hole 10 formed in a first etching process, UV-ray hardening type resin composite material is used. By radiating UV rays immediately after applying the etching resistance material 12, the etching resistance layer 12 of a constant and sufficient film thickness can be formed stably. Processes are simplified because need of a drying process is eliminated, and environmental problems and problems of defective products are prevented.</p> |
