Mardochee Reveil

US Patent:

20230041269, Feb 9, 2023

Filed:

Jul 12, 2022

Appl. No.:

17/862927

Inventors:

- Corning NY, US
Charles Thomas McLaren - Elmira NY, US
Mardochee Reveil - Alexandria VA, US
Nicholas James Smith - Port Matilda PA, US

International Classification:

C03C 23/00
C03C 21/00
C03C 4/18

Abstract:

A glass substrate with modified surface regions is disclosed. The glass substrate includes a first side and an opposite second side, an alkali-containing bulk disposed between the first and second sides, and a first alkali-depleted region formed in the alkali-containing bulk on the first side. The first alkali-depleted region defines at least a portion of a first topographical feature. The first topographic feature includes a height that extends in a first direction from a base portion of the first topographical feature to an outermost portion of the first topographical feature. The first direction is oriented parallel to a thickness of the glass substrate between the first and second sides. The first topographic feature also includes a width that extends in a second direction between at least two, spaced apart wall portions of the first topographical feature. The second direction is oriented normal to the first direction.

C03C 4/18

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.
