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.
