Publication number: 20190276356Abstract: Strengthened glass substrates and methods of reducing warp in strengthened glass substrates having 3D and 2.5D shapes are disclosed. In one embodiment, a strengthened glass-based article includes a first surface, a second surface opposite the first surface, and an edge between the first surface and the second surface. The edge is asymmetric with respect to a plane that is located at an average depth of the strengthened glass-based article and is parallel to the first surface and the second surface. The strengthened glass-based article has an expected warp WE based at least in part on a shape of the asymmetric edge of the strengthened glass-based article. An actual warp WA of the strengthened glass-based article is less than 85% of the expected warp metric WE of the strengthened glass-based article. The actual warp WA of the strengthened glass-based article is measured with a concave surface facing up.Type: ApplicationFiled: November 29, 2017Publication date: September 12, 2019Inventors: John Steele Abbott, Douglas Clippinger Allan, John Martin Darfin, Sumalee Likitvanichkul Fagan, David Lee Weidman, David Inscho Wilcox -

Publication number: 20190010602Abstract: A chucking apparatus and method for vacuum processing mobile device cover substrates in a vacuum chamber in which the chucking apparatus is configured for temporarily securing the cover substrate within the vacuum chamber, and includes a carrier substrate with a CTE within 20% of CTE of the cover substrate to prevent the carrier substrate and the cover substrate from becoming detached from one another due to differing rates of thermal expansion during processing in the vacuum chamber. The carrier substrate has a surface contact area in contact with the cover substrate selected to provide for continuous bonding during the processing in the vacuum chamber and to provide for de-bonding after the process in the vacuum chamber is complete. Further, the carrier substrate is prepared for use with a cleaning process that facilitates Van der Waals bonding between the carrier substrate and the cover substrate.Type: ApplicationFiled: December 29, 2016Publication date: January 10, 2019Inventors: Daniel Robert Boughton, James Gerard Fagan, Sumalee Likitvanichkul Fagan
