Bonded Article of Thin Glass on Support Substrate, Preparation Method and Use Thereof

摘要

A method for making a bonded article, wherein a thin glass substrate is bonded on a support substrate in the absence of any interlayer by an electrostatic adhesion process with the assistance of external pressure, the pressure is applied constantly or stepwise during the adhesion process by use of a tool such as a roll or a wheel or other movable device with curved surface. The bonded article has no defects, e.g. bubbles or inclusions, in the bonded interface, which benefits transportation of the thin glass substrate and its post-processing as well. Such defect-free bonded article is also disclosed. Pressure supported electrostatic adhesion, initiated by electrostatic charges adhesion of a two members, e.g. a substrate member and a support member, is enabled to minimize, prevent and exclude defects, distortion between the adhered surfaces.

主权项

1. A method for making a bonded article, comprising:
providing a support member having a first surface and a second surface; providing a flexible substrate member having a first surface and a second surface; winding the flexible substrate member onto a roller or a device with curved surface; charging the support member and/or the flexible substrate member; and bonding one of the first and second surfaces of the support member to one of the first and second surfaces of the flexible substrate member gradually under rotation and movement of the roller or the device with curved surface by both electrostatic force and mechanical pressure exerted by the roller or the device with curved surface.
