Methods of fabricating glass articles by laser damage and etching

摘要

Methods of forming a glass article are disclosed. In one embodiment, a method of forming a glass article includes translating a pulsed laser beam on a glass substrate sheet to form a laser damage region between a first surface and a second surface of the glass substrate sheet. The method further includes applying an etchant solution to the glass substrate sheet to remove a portion of the glass substrate sheet about the laser damage region. The method may further include strengthening the glass substrate sheet by an ion-exchange strengthening process, and coating the glass substrate sheet with an acid-resistant coating. Also disclosed are methods where the laser damage region has an initial geometry that changes to a desired geometry following the reforming of the glass substrate sheet such that the initial geometry of the laser damage region compensates for the bending of the glass substrate sheet.

1. A method of forming a glass article, comprising:
providing a glass substrate sheet; translating a pulsed laser beam on the glass substrate sheet to form a laser damage region extending from a first surface of the glass substrate sheet to a second surface of the glass substrate sheet, wherein:
the laser damage region comprises a plurality of defect lines, wherein each defect line is formed at a different depth of the glass substrate sheet; and applying the glass substrate sheet with an etchant solution comprising about 1M to about 3M of hydrofluoric acid and hydrochloric acid, wherein:
a concentration of the hydrochloric acid is less than about 1M if a concentration of the hydrofluoric acid is greater than about 2M; andthe concentration of the hydrochloric acid is between about 1M and about 3M if the concentration of the hydrofluoric acid is less than about 2M.
