Abstract: A method of making an antimicrobial glass article that includes the steps: submersing the article in a strengthening bath to exchange a portion of ion-exchangeable metal ions in the glass article with a portion of ion-exchanging metal ions in the strengthening bath to form a compressive stress layer extending from the first surface to a diffusion depth in the article; removing a portion of the compressive stress layer from the first surface of the article to a first depth above the diffusion depth in the article to define a new first surface and a remaining compressive stress layer; and submersing the article in an antimicrobial bath to exchange a portion of the ion-exchangeable and the ion-exchanging metal ions in the compressive stress layer with a portion of the silver metal ions in the antimicrobial bath to impart an antimicrobial property in the article.

Abstract: Disclosed herein are glass-based articles having a first surface having an edge, wherein a maximum optical retardation of the first surface is at the edge and the maximum optical retardation is less than or equal to about 40 nm and wherein the optical retardation decreases from the edge toward a central region of the first surface, the central region having a boundary defined by a distance from the edge toward a center point of the first surface, wherein the distance is ½ of the shortest distance from the edge to the center point.

Abstract: A glass-based article includes a first major surface and a first compressive stress region extending to a first depth of compression from the first major surface. The glass-based article includes a second major surface including a first surface portion and one or more edge surface portions recessed from the first surface portion. The glass-based article includes a second compressive stress region extending to a second depth of compression from the first surface portion. Additionally, methods of manufacturing a glass-based article are disclosed.

Abstract: A chucking apparatus and method for vacuum processing mobile device cover substrates in a vacuum chamber in which the chucking apparatus is configured for temporarily securing the cover substrate within the vacuum chamber, and includes a carrier substrate with a CTE within 20% of CTE of the cover substrate to prevent the carrier substrate and the cover substrate from becoming detached from one another due to differing rates of thermal expansion during processing in the vacuum chamber. The carrier substrate has a surface contact area in contact with the cover substrate selected to provide for continuous bonding during the processing in the vacuum chamber and to provide for de-bonding after the process in the vacuum chamber is complete. Further, the carrier substrate is prepared for use with a cleaning process that facilitates Van der Waals bonding between the carrier substrate and the cover substrate.

Abstract: A chucking apparatus and methods for coating a glass substrate using a vacuum deposition process are disclosed. In one or more embodiments, the chucking apparatus includes an ESC (ESC), a carrier disposed on the ESC, wherein the carrier comprises a first surface adjacent to the ESC and an opposing second surface for forming a Van der Waals bond with a third surface of a glass substrate, without application of a mechanical force on a fourth surface of the glass substrate opposing the third surface. In one or more embodiments, the method includes disposing a carrier and a glass substrate on an ESC, such that the carrier is between the glass substrate and the ESC to form a chucking assembly, forming a Van der Waals bond between the carrier and the glass substrate, and vacuum depositing a coating on the glass substrate.

Abstract: Described herein are various methods and manufacturing methods for making antimicrobial and strengthened, antimicrobial glass articles and substrates. The methods described herein generally include contacting the article with a KNO3-containing molten salt bath set at about 380 C to about 460 C for about 30 minutes to about 24 hours to form a compressive stress layer that extends inward from a surface of the glass substrate to a first depth; and contacting the article comprising the compressive stress layer with a AgNO3-containing molten salt bath set at about 300° C. to about 400° C. for about 5 minutes to about 18 hours to form an antimicrobial region that extends inward from the surface of the glass substrate to a second depth. The methods also include poisoning at least the AgNO3-containing molten salt bath and, in some cases, the KNO3-containing molten salt bath. Poisoning components include Na+ and Li+ ions.
