Abstract
PURPOSE: To lessen the dispersion of the demensional accuracy of products by the method in which pattern dimension between the both sides of a plate is differentiated by closely adhering the photosensitive membrane on one side to negative plate and also by inserting a transparent plate into between the photosensitive membrane on another side and the negative plate.
CONSTITUTION: The both sides of a metal plate 41, as of stainless steel, etc., are provided with the photosensitive membranes 42 and 43. And, the negative plate 44 and 45 having a fixed pattern made by transferring from the same plate are placed on the photosensitive membranes 42 and 43, where the base plate 46 is adhered to the negative plate 44 and these are closely adhered to the photosensitive membrane in such a way that the photosensitive membrane 43 on the one side is closely adhered to the negative plate 45 and also a transparant base plate 46 of an appropriate thickness is put between the photosensitive membrane 42 on another side and the negative plate 44. Then, the plate is exposed to light by using a superhigh pressure mercury lamp, etc., in the direction of the arrow marks, followed by etching with fixed processes. Thus, the width of the pattern 47 on the side of the transparent base plate 46 is made to become greater than the pattern 48 of the other side, and therefore adjusting divergence is absorbed, thus resulting in the enhancement of finished dimensional accuracy of mesh.
