A method of texturing a glass surface is disclosed, the method comprising the steps of coating the glass surface with a material film, stimulating a reaction at the interface between the glass and the material film resulting in the formation of reaction products at the interface, and removing the material film and the reaction products from the glass surface. In a preferred embodiment, an aluminium film around 500nm thick aluminosilicate is coated onto the glass and the stimulation is by heating. The aluminium reacts with the silica at temperatures between 500°C and 630°C to form reaction products that are then removed, along with the film, by etching with phosphoric acid. A further etch using HF/HNO3 may also be employed. The method is particularly useful in etching glass substrates intended for use in photovoltaic devices.

A process for manufacture of a second surface optically recordable disk having ultraviolet (UV) inhibiting characteristics is disclosed. A reflective laminate sheet of aluminum, superimposed on a glass laminate substratum, is flow process produced by pyrolysis and precipitation of a layer of aluminum from gasified triisobutyl aluminum onto a laminate web of silicate (amorphous glass) which is concomitantly pyrolized from tetraethoxy silane, with or without alkoxide additives, and precipitated upon a flowing body of molten tin to form a dual laminate sheet. To complete the process, an optically active layer which is applied over the reflective layer is embossed with optically transparent ultraviolet (UV) inhibiting polycarbonate, protective covers, the mating surfaces of which, maybe, pregrooved and coded to form second surface optically active media. Covers with bonded laminates are then successively severed from the laminate sheet to yield independent second surface optically recordable media.

摘要:
A method for forming a pattern, for example, an electrically conducting pattern on a glass window, comprises the steps of depositing on the ceramic substrate (12) in a desired pattern a thin layer (16) of a heat fusable material. A protective layer (26) is deposited over the pattern formed of the heat fusable material. The protective layer (26) may be formed from an oxygen barrier material and an oxygen getting material. The protective layer (26) is non-heat fusable and nonreactive with the heat fusable material (16). All of this structure can then be heated in an oxygen containing atmosphere to a temperature sufficient to permit the heat fusable material (16) to fuse to the ceramic substrate (12). The protective layer protects the fusable material from oxidation by physically blocking out oxygen and by chemically providing an oxygen getting material which will react with any oxygen which does manage to penetrate into the oxygen barrier material. The ceramic substrate (12), fused heat fusable material (16), and remaining oxygen barrier material (26) thereon are cooled back to room temperature and any remainder of the protective layer (26) is removed from the ceramic substrate (12).
