System and method for cleaning surface of substrate using roll-to-roll plasma generating device

A roll-to-roll plasma surface cleaning treatment system, comprising:

• an upper housing containing a first plasma generating device and a first transfer roller that faces a nozzle from which a plasma beam generated by the first plasma generating device is discharged and that winds and transfers a flexible substrate, the upper housing comprising a gas inlet, an entrance through which the flexible substrate is introduced, and an outlet through which the flexible substrate is discharged;
• and
• a lower housing connected to the entrance of the upper housing and containing a second plasma generating device and a second transfer roller that faces a nozzle from which a plasma beam generated by the second plasma generating device is discharged and that winds and transfers the flexible substrate, the lower housing comprising a gas outlet, and an inlet through which the flexible substrate is introduced,
• wherein the system is configured to maintain the upper housing at a low-temperature atmosphere by introducing a low-temperature refrigerant gas through the gas inlet.
