According to one embodiment, a method for producing a coated glass article may include applying an anti-reflective coating onto a glass substrate. The glass substrate may include a first major surface, and a second major surface opposite the first major surface. The anti-reflective coating may be applied to the first major surface of the glass substrate. A substrate thickness may be measured between the first major surface and the second major surface. The glass substrate may have an aspect ratio of at least about 100:1. The coated glass article may have a reflectance of less than 2% for all wavelengths from 450 nanometers to 700 nanometers. The anti-reflective coating may include one or more layers. The cumulative layer stress of the anti-reflective coating may have an absolute value less than or equal to about 167,000 MPa nm.

Coated glass articles and processes for producing the same

Methods of processing a first substrate bonded to a second substrate include moving a wire along an interface to propagate a debonding front and debond the first substrate from the second substrate. In some embodiments, the first substrate includes a thickness less than or equal to about 300 &#x3bc;m. In further embodiments, the wire includes a tensile strength less than a critical failure stress of the first substrate. In still further embodiments, the wire is configured to conform to a shape of the debonding front during the step of moving the wire such that one or more edges of the first substrate are debonded from the second substrate prior to a debonding of a corresponding interior portion of the first substrate from the second substrate.
