Patent number: 11242281Abstract: The invention relates to a glass substrate for chemical strengthening where a surface is coated by magnetron sputtering with a temporary thin film that reduces the extent of ion exchange upon chemical strengthening and where the temporary thin film can be removed after the chemical strengthening by treatment with an etchant solution. Other embodiments relate to a method for making a chemically strengthened glass substrate with controlled curvature comprising: providing a substrate with opposed surfaces that are durable to a given etchant solution, forming a temporary thin film upon at least part of a surface of the glass substrate, chemically strengthening the glass substrate bearing the temporary thin film, and removing the temporary thin film after said chemical strengthening with said etchant solution.
