Abstract

PURPOSE:To improve the dimensional accuracy of a deposited film and enable fine working in a pattern forming method by a lift-off method in vacuum deposition by providing a two-layer photoresist film in an eave shape for covering via Al on a substrate and carrying out deposition. CONSTITUTION:The first photoresist 1 is applied to a substrate 5, then Al 3 is deposited all over the surface, and further on it, the second photoresist 2 different from the first one is applied. The first and the second photoresists have developers which do not react with each other. Exposing and developing the second photoresist 2 selectively using a mask, then overetching the Al and exposing and developing the first photoresist 1, an eave-shaped covering film can be formed, and by depositing using this film, the dimensional accuracy of a deposited film can be improved, so that fine working can be performed.
