Claims
- 1. In a method of forming a thick film pattern of ceramic material on a supporting substrate, the method comprising the steps of:
- coating ultraviolet curing resin on an original plate having a concave-convex surface corresponding to a desirable pattern;
- providing and extending a substrate film on said ultraviolet curing resin;
- forming a tentative female mold having a groove with a desirable pattern on said substrate film after curing said ultraviolet curing resin by ultraviolet rays and removing the same from said original plate;
- causing said tentative female mold carrying said substrate film to adhere to said substrate in such a manner that said groove is in confrontation with said supporting substrate;
- removing the upper portion of said tentative female mold after removing said substrate film from said tentative female mold to define a final female mold having a desirable pattern with upwardly open spaces on said supporting substrate;
- filling said ceramic material in only the upwardly open spaces formed in said final female mold; and
- calcining to cause said final female mold to vanish.
- 2. The method of claim 1, wherein the step of causing the tentative female mold to adhere to said supporting substrate comprises the steps of:
- bringing said tentative female mold in contact with said supporting substrate; and
- irradiating said ultraviolet rays onto said tentative female mold.
