摘要:
An electronic device material preform is used when manufacturing an electronic device material where a predetermined functional layer is formed on a surface of a substrate by sputtering. The electronic device material preform includes a discharge-guiding film that conducts electricity and guides abnormal discharge that occurs when the sputtering is carried out. The discharge-guiding film is formed at a predetermined part of an outer circumferential edge of the substrate before the functional layer is formed.
