Abstract: PURPOSE:To enable to accurately form a pattern even when an oblique stepwise difference is provided on a circuit substrate by forming two layers on a layer to be formed, coating the layer with a photosensitive film, and selecting the complex refractive indexes of these layers and film to suitable values. CONSTITUTION:A layer 22 to be formed which has n0-ik0 of complex refractive index for photosensitive ultraviolet light is formed on a circuit substrate 21 which has a stepwise difference including an oblique. Then, layers 27, 28 which respectively have complex refractive indexes n1-ik1, n2-ik2 are formed on the layer 22, and a photosensitive film 23 which has a complex refractive index of n3-ik3 is formed thereon. In this case, the materials of the layeys 27, 28 are selected so as to satisfy a relationship of n3<=n2<=n1 in the real parts of the complex refractive indexes of the respective layers. Thus, since the reflectivity of ultraviolet light reflected on the oblique of the layer 22 is suppressed and several %, most of it is absorbed by the layer 27, 28 to prevent the damage of the film 23, the forming accuracy of the layer 22 can be improved.
