<P>PROBLEM TO BE SOLVED: To provide a method for film formation by which a laminate can be efficiently produced, the laminate on which vacuum film formation is applied to double sides by suitably performing heating treatment or the like using a simple device constitution. <P>SOLUTION: The film formation method comprises the steps of: unrolling and feeding an elongated substrate wound in a roll form from a first roll chamber W1 in a first direction from the first roll chamber W1 toward a second roll chamber W2; degassing the fed substrate 10; forming a first material film on a first surface in a first film formation chamber 41; guiding the substrate having the first material film formed thereon to a second film formation chamber 42 in a second direction from the second roll chamber toward the first roll chamber; forming, in the second film formation chamber, a second material film on a second surface opposite the first surface of the substrate when it is being guided in the second direction; taking up, in a third roll chamber W3 provided between the first roll chamber and the second roll chamber, the substrate in a roll state, the substrate having the first material film formed on the first surface and the second material film formed on the second surface; unrolling and feeding the substrate taken up in the third roll chamber from the first roll chamber in the first direction; and repeating all the above treatments. <P>COPYRIGHT: (C)2013,JPO&INPIT |
