Patent number: 10086584Abstract: Surface modification layers and associated heat treatments, that may be provided on a sheet, a carrier, or both, to control both room-temperature van der Waals (and/or hydrogen) bonding and high temperature covalent bonding between the thin sheet and carrier. The room-temperature bonding is controlled so as to be sufficient to hold the thin sheet and carrier together during vacuum processing, wet processing, and/or ultrasonic cleaning processing, for example. And at the same time, the high temperature covalent bonding is controlled so as to prevent a permanent bond between the thin sheet and carrier during high temperature processing, as well as maintain a sufficient bond to prevent delamination during high temperature processing.Type: GrantFiled: October 7, 2013Date of Patent: October 2, 2018Assignee: Corning IncorporatedInventors: Robert Alan Bellman, Dana Craig Bookbinder, Robert George Manley, Prantik Mazumder, Theresa Chang, Jeffrey John Domey, Darwin Gene Enicks, Vasudha Ravichandran, Alan Thomas Stephens, II, John Christopher Thomas
