The invention relates to a method and an etching reagent for the wet-chemical etching of TiO2 thin-films and TiO2particles that permits a defined removal of the TiO2thin-film and a reduction of the particle size. The method comprises the steps: production of an etching reagent with a pH value greater than 13, said reagent containing a base with a concentration of > 0.1 mol, selected from the bases NH4OH, NaOH, KOH or mixtures of the same and H2O2 with a smaller concentration than that of the base; setting of a temperature that is equal to or greater than the ambient temperature; immersion of the TiO2 thin-films and TiO2 particles in the etching reagent and steeping of the layers of the TiO2 thin-films and particles; said films and particles are then rinsed with distilled water and dried. To maintain the initial composition of the etching reagent, H2O2 is added during the etching process.

A microstructured optical fiber exhibiting enhanced circularity of the guided light mode is provided. The microstructured optical fiber includes a light-guiding core and a primary cladding surrounding the core wherein the primary cladding has a plurality of holes arranged in hexagonal unit cells defining an Archimedean-like lattice. Preferably, the core is defined by a break in a center of the Archimedean- like lattice, the break being characterised by an absence of at least one of the unit cells. Also preferably, each of the unit cells has seven holes arranged in a centred hexagon. A method of making the microstructured optical fiber is also provided. The method includes fabricating a fiber preform by stacking a plurality of canes around a rod, each cane having a number of holes arranged in a unit cell defining an Archimedean-like lattice, and drawing said fiber preform into the microstructured optical fiber.

A method is provided for patterning monolithically integrated features having a 1:1 ratio. The method comprises forming a first etch barrier layer (18) over a base layer (14) and applying (52) a template (20) to pattern (52) first printed features (26) in the first etch barrier layer (18). The first etch barrier layer (18) is etched (54) to form second printed features (32) in the base layer (14). A second etch barrier layer (34) is formed over the base layer (14) and the template (20) is applied to pattern (58) third printed features (38) in the second etch barrier layer (34). The second etch barrier layer (34) is etched (60) to form fourth printed features (42) in the base layer (14).

The invention relates to a panel made of glass for roofs and/or vertical walls for greenhouses for growing crops. On at least one side, the panel is provided with a structured surface which is formed by indentations formed in the glass, with the depth of the various indentations in the panel being between 1 and 100 micrometres. The indentations formed in the panel are of an at least substantially equal depth. The centre- to-centre distance between adjacent indentations is between 1 and 100 microns.
摘要:
A method and system for processing a substrate includes providing the substrate in a process chamber, the substrate having an oxide layer formed thereon, and exposing the substrate to an etching gas containing F 2 gas at a first temperature to remove the oxide layer from the substrate. The substrate may subsequently be heated to a second temperature greater than the first temperature, and a film may then be formed on the substrate at the second temperature. In one embodiment, a Si film is epitaxially formed on a Si substrate.
