Abstract

A vacuum deposition apparatus is used for deposit evaporated substance from evaporation sources (6a and 6b) on the desired position of a flexible substrate (1). While the flexible substrate (1) is carried using rollers in a vacuum, shutters (8a and 8b) are opened and closed to control the movement of the evaporated substance via openings. A film having a desired shape of pattern is formed on the flexible substrate (1) with higher controllability.
