Abstract: A method of fabricating a metal thin film-on-glass structure. A glass substrate, on a top surface of which a layer is formed, is prepared. A local area of the glass substrate is etched from a bottom of the glass substrate to expose the layer downwardly, thereby forming an exposed area of the layer. The layer is a metal thin film. The etching includes first-etching the glass substrate to a depth less than a thickness of the glass substrate using a first etching solution containing hydrofluoric acid and at least one of nitric acid and sulfuric acid, resulting in a first-etched portion of the glass substrate; and second-etching the first-etched portion of the glass substrate using an etching solution containing hydrofluoric acid without nitric acid or sulfuric acid, so that the layer is exposed downwardly, whereby the metal thin film is supported by a remaining portion of the glass substrate.

Abstract: Ceramic assembly can comprise a ceramic article comprising a thickness defined between a first major surface and a second major surface. The thickness can be about 100 micrometers or less. The ceramic assembly can comprise a polymer coating deposited over at least an outer peripheral portion of the first major surface of the ceramic article. The polymer coating can comprise a thickness of about 30 micrometers or less. An edge strength of the ceramic assembly can be greater than an edge strength of the ceramic article by about 50 MegaPascals or more. Methods of forming a ceramic assembly can comprise depositing a polymer coating on an outer peripheral portion of a first major surface of a ceramic article. Methods can further comprise curing the polymer coating.

Abstract: A vacuum insulated glass unit (IGU) including an interconnected polymer spacer matrix and methods of making the same. The vacuum IGU includes a first glass-based layer, a second glass-based layer, an interconnected polymer spacer matrix, and an edge seal between the periphery of the first and second glass-based layers.
