FILM FORMATION DEVICE

摘要

The present invention is to provide a technology for forming an organic compound film having a uniform thickness on a film at a high film formation speed while transporting the film in a vacuum chamber. In a vacuum chamber, a film reeled out from a mother roll is transported in contact with a center roller and an organic compound film is formed on the film. A vapor emission device disposed in a film deposition chamber provided in the vacuum chamber and having a vapor emission unit which emits and blows a vapor of an organic compound monomer to a film on the center roller, and an energy ray-emitting device for irradiating an organic compound monomer layer formed on the center roller with an energy ray so as to cure the organic compound layer are provided. The vapor emission device and the film deposition chamber are respectively connected to fifth and third vacuum evacuation devices which are independently controllable; and the pressure in the vapor emission device is set to be larger than the pressure in the film deposition chamber. The difference between the pressure in the vapor emission device and the pressure in the film deposition chamber is set to be constant.
