Abstract: A roll to roll fabrication apparatus includes: a vacuum chamber having an installation chamber and a process chamber; a preprocessing unit in the installation chamber to process a surface of a film which is transferred to enhance a film characteristic in a subsequent CVD process; a process drum in the process chamber to wind the film thereon; a process treatment unit in the process chamber to form a layer by performing a CVD process on the film wound on the process drum; and a plurality of heaters in the installation chamber and the process chamber to gradually increase a temperature of the film wound on the process drum to prevent application of a thermal impact to the film due to the high-temperature process drum.

Abstract: Disclosed herein is a drum for roll-to-roll deposition to rotate about a longitudinal axis. The drum is circular in a widthwise cross-section and has a shape in which opposite longitudinal edge portions each have a narrower width than a longitudinal central portion. By using the drum for roll-to-roll deposition according to embodiments of the present disclosure, it is possible to remove wrinkles occurring on a flexible substrate when a roll-to-roll deposition process is performed. As a result, it is possible to manufacture a film roll having a deposition layer with excellent widthwise thickness uniformity.
