  • Publication number: 20070134426
    Abstract: The invention provides a vacuum evaporation deposition method of the winding type and a vacuum evaporation deposition apparatus of the winding type which can form a metal film on a base film made of a single layer of insulating material such as plastic film without thermal deformation, and which is superior in productivity. An electron beam irradiator 21 irradiates an electron beam onto an insulating material base film 12 before deposition of metal, and a DC bias power source 22 applies bias voltage between an auxiliary roller 18 for guiding the base film 12 with metal film deposited thereon and a can roller 14, whereby the base film 12 charged by the irradiation of the electron beam before the deposition of metal film, is made to be in close contact with the can roller 14. The base film 12 after deposition of metal film is made to be in close contact with the can roller 14 by the bias voltage applied between the auxiliary roller 18 connected electrically to the metal film and the can roller 14.
