    Abstract: Embodiments of this disclosure pertain to a strengthened glass article including a first surface and a second surface opposing the first surface defining a thickness (t) of about less than about 1.1 mm, a compressive stress layer extending from the first surface to a depth of compression (DOC) of about 0.1·t or greater, such that when the glass article fracture, it breaks into a plurality of fragments having an aspect ratio of about 5 or less. In some embodiments, the glass article exhibits an equibiaxial flexural strength of about 20 kgf or greater, after being abraded with 90-grit SiC particles at a pressure of 25 psi for 5 seconds. Devices incorporating the glass articles described herein and methods for making the same are also disclosed.

    Abstract: A glass structure and a method for creating the glass structure include a glass carrier layer and a flexible glass substrate. The glass structure includes an intermediate layer at least temporarily bonding the flexible glass substrate to the glass carrier layer. The intermediate layer includes a first debond layer attached to an adhesion layer. The first debond layer is at least partially resistant to a high temperature processing of the glass structure at a temperature of greater than or equal to about 500° C. The first debond layer is configured to enable the flexible glass substrate to be debonded from the glass carrier layer after the high temperature processing of the glass structure. A method for processing the glass structure includes debonding the flexible glass substrate from the glass carrier layer after the high temperature process.
