Thin-film devices, for example electrochromic devices for windows, and methods of manufacturing are described. Particular focus is given to methods of patterning optical devices. Various edge deletion and isolation scribes are performed, for example, to ensure the optical device has appropriate isolation from any edge defects. Methods described herein apply to any thin-film device having one or more material layers sandwiched between two thin film electrical conductor layers. The described methods create novel optical device configurations.

An electronic component has an organic member between two transparent substrates, in which outer peripheral portions of the two transparent substrates are bonded by a sealing material containing to melting glass. The low melting glass contains vanadium oxide, tellurium oxide, iron oxide and phosphoric acid, and satisfies the following relations (1) and (2) in terms of oxides. The sealing material is formed of a sealing material paste which contains the low melting glass, a resin binder and a solvent, the low melting glass containing vanadium oxide, tellurium oxide, iron oxide and phosphoric acid, and satisfies the following relations (1) and (2) in terms of the oxides. Thereby, thermal damages to an organic element or an organic material contained in the electronic component can be reduced and an electronic component having a glass bonding layer of high reliability can be produced efficiently.

Certain aspects pertain to methods of fabricating an optical device on a substantially transparent substrate that include a pre-deposition operation that removes a width of lower conductor layer at a distance from the outer edge of the substrate to form a pad at the outer edge. The pad and any deposited layers of the optical device may be removed in a post edge deletion operation.

A method for producing a composite glass pane, includes placing a first glass pane having a thickness less than or equal to 1 mm on a support mould, wherein the first glass pane is curved into a shape determined by the support mould; placing at least one thermoplastic film on the first glass pane; placing a curved second glass pane having a thickness greater than or equal to 1.5 mm on the thermoplastic film; and joining the first glass pane to the second glass pane via the thermoplastic film to form a composite glass pane by lamination.

A glass laminate comprises an external glass sheet, an internal glass sheet, and a polymer interlayer formed between the external glass sheet and the internal glass sheet. The external glass sheet can be a thin chemically-strengthened glass sheet or can be a non-chemically strengthened glass sheet, the polymer interlayer can have a thickness of less than 1.6 mm, and the internal glass sheet can be a non-chemically-strengthened glass sheet or a thin chemically strengthened glass sheet.

A laminated glazing unit includes a first sheet of soda-lime-silica mineral glass having a thickness e1 of between 1.5 mm and 2.5 mm, a second sheet of mineral glass and a lamination interlayer, the first and second mineral glass sheets being adhesively bonded together by the lamination interlayer. The second mineral glass sheet is a sheet of soda-lime-silica mineral glass having a thickness e2 of between 0.4 and 1.1 mm, the second sheet of soda-lime-silica mineral glass being chemically toughened. A surface compressive stress of the second sheet of soda-lime-silica mineral glass is between 350 MPa and 550 MPa and a ratio R=e1/e2.sup.2 is at most 20 mm.sup.−1.

Transparent or translucent sound diffusers include a first glass sheet of less than 0.8 mm thickness and a second glass sheet of less than 0.8 mm thickness with a transparent or translucent adhesive layer there between, the adhesive layer adhering the first and second sheets in a fixed configuration such that a first major surface of the first glass sheet has a smooth, repeatedly rising and falling shape. The diffusers are secured to a wall or ceiling or to a wall or ceiling mount or to a wall or ceiling panel.

Disclosed herein are embodiments of a borosilicate glass composition as may be useful for windshield and other applications in particular due to unique fracture behavior.
