Abstract: Multilayer anti-reflective coatings having four or more layers are disclosed. In one aspect, the multilayer anti-reflective coating comprises a first layer having a refractive index n1, where n1<1.4, and an optical thickness of (0.25±5%) ?o nm; a second layer adjacent to the first layer, the second layer having a refractive index n2, where n2?1.8, and an optical thickness of (0.5±5%) ?o nm; a third layer adjacent to the second layer, the third layer having a refractive index n3, where 1.4?n3<1.6, and an optical thickness of (0.1±5%) ?o nm; and a fourth layer adjacent to the third layer, the fourth layer having a refractive index n4, where n4?1.8, and an optical thickness of (0.05±10%) ?o nm; where ?o is a wavelength in the visible light range.

Abstract: Methods and apparatus provide for: disposing an intermediate layer formed from at least one of: a metal, a conductive oxide, and combined layers of the metal and the conductive oxide, on one of a first material layer and a second material layer; and coupling the first and second material layers together via an anodic bond between the intermediate layer and the other of the first and second material layers.

Abstract: The invention is directed to a method of protecting a glass surface during transportation and/or process using an aqueous solution of an acrylic material to protectively coat the surface of the glass sheet. The acrylic protective coating may be applied by dipping, roller applying or spraying the coating on the glass. The coating is then cured, dried or baked in an oven. Subsequently, the glass sheet may be scored and separated into individual glass article blanks for further processing; for example, edge grinding to produce smooth edges and drilling/milling to produce openings such as holes in the surface of the glass. When processing of the glass article is completed, the protective coating can be removed or the article can be shipped to the end used who can remove the coating using an aqueous solution of pH?12 to remove the coating.

Abstract: An alkali aluminosilicate glass article, said alkali aluminosilicate glass having a surface compressive stress of at least about 200 MPa, a surface compressive layer having a depth of at least about 30 ?m, a thickness of at least about 0.3 mm and an amphiphobic fluorine-based surface layer chemically bonded to the surface of the glass. In one embodiment the glass has an anti-reflective coating applied to one surface of the glass between the chemically strengthened surface of the glass and the amphiphobic coating. In another embodiment the surface of the chemically strengthened glass is acid treated using a selected acid (e.g., HCL, H2SO4, HClO4, acetic acid and other acids as described) prior to placement of the amphiphobic coating or the anti-reflective coating.

Abstract: The invention is directed to a hermetically sealed device and a method for making such device. The device includes optical, micro-electromechanical, electronic and opto-electronic devices, having a substrate with one or a plurality of optical, opto-electronic, electronic or micro-electromechanical (“MEMS”) elements either singly or in combination that are located on a substrate; a covering having a top part and an extension extending a distance from the top part from the top part, an adhesive that is used to bond the extension portion of the covering to the substrate; and a sealing agent for hermetically sealing the area where the covering extension is bonded to the substrate. In the method of the invention the sealing agent is applied using atomic layer deposition techniques.

Abstract: A copper-gallium alloy is deposited on a nonconductive substrate, such as glass, ceramic, or polymeric material, to provide a conductor to which solder will readily adhere, such that electrical contacts to photonic and electrical components can be made. The copper-gallium thin film can also be used to provide a surface for solder sealing a component within a hermetically sealed enclosure. In a preferred embodiment, the copper-gallium alloy was from about 1 to about 40 percent gallium to about 99 to about 60 percent copper and was deposited to a thickness of from about 400 nanometers to about 3 microns. The copper-gallium film is deposited utilizing sputtering or electron beam deposition equipment.
