Patent ID: 10214000

Abstract:
The present invention provides a method for applying a film in which non-contact repulsive forces generated by ultrasonic vibration are applied using an ultrasonic vibration unit (A) to a surface of a substrate so as to support the surface of the substrate without contact, and a film is pressed and applied to the other surface of the substrate using a pressing roller. The ultrasonic vibration unit (A) may comprise: an ultrasonic vibration body facing a surface of the substrate; and an ultrasonic excitement unit for exciting the ultrasonic vibration body. In addition, the present invention provides an apparatus for applying a film comprising: an ultrasonic vibration unit (A) for applying non-contact repulsive forces generated by the ultrasonic vibration to a surface of a substrate so as to support the surface of the substrate without contact; and a pressing roller for pressing and applying a film to the other surface of the substrate.
