Abstract
PURPOSE:To make the formation of a fine pattern such as precision wiring possible by a method wherein two layers of photoresist is used as the spacer of the lifting-off method. CONSTITUTION:After the first photoresist layer 8 is formed on the silicone dioxide film 2 on the surface of a silicone substrate 1, the layer is exposed using the specfied masking pattern, then the second photoresist layer 10 is formed and exposed using the masking pattern of smaller width. After that, by developing process, spacer like a eaves is formed over the aperture. When Al layer is formed, it is divided into 12 and 13 by the spacer, so that electrode wiring 13 can be formed by removing the photoresist layer.
