Abstract
A glass substrate with modified surface regions is disclosed. The glass substrate includes an alkali-containing bulk, a first alkali-depleted region, a second alkali-depleted region, and a first ion-exchanged region. The alkali-containing bulk has a first surface and a second surface with the first and second surfaces on opposite sides. The first alkali-depleted region extends into the alkali-containing bulk from the first surface. The second alkali-depleted region extends into the alkali-containing bulk from the second surface. The first ion-exchanged region extends into the alkali-containing bulk from the first surface. The first alkali-depleted region, the second alkali-depleted region, and the first ion-exchanged region each have a substantially homogenous composition. A method of forming the glass substrate is disclosed. The method includes simultaneously forming the first alkali-depleted region and the first ion-exchanged region in the first surface. The method also includes near-simultaneously forming the second alkali-depleted region in the second surface.
