ARTICLES OF CONTROLLABLY BONDED SHEETS AND METHODS FOR MAKING SAME
20190184686 · 2019-06-20 ·

Described herein are articles and methods of making articles, for example glass articles, comprising a thin sheet and a carrier, wherein the thin sheet and carrier are bonded together using a modification (coating) layer, for example an aromatic polymer coating layer, and associated deposition methods and inert gas treatments that may be applied on the thin sheet, the carrier, or both, to control van der Waals, hydrogen and covalent bonding between the thin sheet and the carrier. The modification layer bonds the thin sheet and carrier together with sufficient bond strength to prevent delamination of the thin sheet and the carrier during high temperature processing while preventing a permanent bond during high temperature processing.

Multifunctional materials for temporary bonding
12024594 · 2024-07-02 · ·

The materials and methods disclosed can be used for applications such as temporary bond and debond of semiconductor and display substrates. These materials have sufficiently low melt rheologies to be used as a bonding layer and can crosslink/cure to allow for reduction in material flow over long periods of time. This class of materials also incorporates the ability to be used as a single-layer system for debonding purposes and typically uses laser debonding for its release mechanism. These materials also allow for solvent cleanability using very mild acidic conditions instead of the typical harsh conditions used on curable layers.
