Abstract
A film deposition apparatus includes: a chamber having a film deposition gas introduced thereinto and exhausted therefrom, in which film deposition with the film deposition gas is performed on an object to be treated; and a film conveying part disposed in the chamber and conveying in a roll-to-roll manner a long film that is the object to be treated. The film conveying part includes: a rotatable roller with part of whose peripheral surface the long film comes into contact; and a nozzle pipe for spraying an inert gas onto a region of the roller, the region being not covered by the long film.

A film deposition apparatus, comprising:
- a chamber having a film deposition gas introduced thereinto and exhausted therefrom, wherein film deposition with the film deposition gas is performed on an object to be treated;
- and
- a film conveying part disposed in the chamber and conveying a long film in a roll-to-roll manner, the long film being the object to be treated;
- wherein,
- the film conveying part includes:
- a rotatable roller, the long film coming into contact with part of a peripheral surface of the roller;
- and
- a nozzle pipe for spraying an inert gas onto a region of the roller, the region being not covered by the long film.

- and
- a film conveying part disposed in the chamber and conveying a long film in a roll-to-roll manner, the long film being the object to be treated;
- wherein,
- the film conveying part includes:
- a rotatable roller, the long film coming into contact with part of a peripheral surface of the roller;
- a bearing part rotatably supporting a shaft of the roller;
- and
- a heater raising a temperature of the bearing part to a temperature not allowing the film deposition gas to be adhered to the shaft.

- a film conveying part disposed in the chamber and conveying a long film in a roll-to-roll manner, the long film being the object to be treated;
- wherein,
- the film conveying part includes:
- a rotatable tension detection roller, the long film coming into contact with part of a peripheral surface of the tension detection roller;
- a tension sensor detecting tension of the long film based on external force acting on the tension detection roller;
- and
- a case including a slit, the slit having the part of the peripheral surface of the tension detection roller exposed, and surrounding both the tension detection roller except the part of the peripheral surface and the tension sensor;
- wherein,
- into the case, an inert gas is introduced at a pressure higher than a pressure in the chamber.
