Vacuum peeling apparatus and method

摘要

The invention relates generally to a vacuum peeling apparatus and a vacuum peeling method. The vacuum peeling apparatus may include a chamber, a sealing maintain frame disposed inside the chamber, a first air tube disposed along a bottom end of the sealing maintain frame and configured to be expandable, a peeling prevention panel configured so as to be inserted into a center of the sealing maintain frame, and a second air tube disposed along an end of the peeling prevention panel.

主权项

1. A vacuum peeling method, comprising the steps of:
preparing a target object, wherein the target object includes a substrate, a first film disposed on a top surface of the substrate, and a second film disposed on a bottom surface of the substrate, and wherein an edge of the first film is connected to an edge of the second film so as to form connected edges of the first film and the second film; disposing the target object inside a chamber having an atmospheric pressure; pressurizing the connected edges of the first film and the second film of the target object using a sealing maintain frame; pressurizing the first film disposed on a top surface of the target object by inserting a peeling prevention panel into the sealing maintain frame; forming a sealing space surrounded by the target object, the sealing maintain frame, and the peeling prevention panel; changing an inside pressure of the chamber to a vacuum pressure while maintaining an inside pressure of the sealing space at the atmospheric pressure; changing the inside pressure of the sealing space to the vacuum pressure; and separating the first film from the substrate while maintaining the connected edges of the first film and the second film of the target object by lifting the peeling prevention panel.
