Abstract: A method for structured coating of a surface of a substrate. The surface includes spaced optical elements and at least partially metallic elements provided adjacent the optical elements. After the application of the method, the optical elements should be completely covered with the coating, whereas at least some of the metallic elements should not be coated on the major part of their surface. The method includes: a) providing the substrate with the spaced optical elements and metallic elements; b) applying a sacrificial material to at least some of the metallic elements to form sacrificial spots; c) coating the surface of the substrate with a layer system; and d) detaching the sacrificial spots from the substrate, wherein the regions of the layer system on the sacrificial spots are also detached from the substrate. The application of the sacrificial material is carried out at least partially by jetting.

Abstract: An optical filter having a substrate including a primary bandpass filter at least predominantly on an interference basis and a secondary bandpass filter at least predominantly on an interference basis. Both bandpass filters are designed such that they transmit sufficiently over the entire required angle range in the desired spectral transmittance wavelength interval. The primary bandpass filter contains the small angle shift required by the overall system. It also has a spectral transmittance wavelength interval which is as small as possible according to the requirements of the respective application and restricted by narrow blocking bands. The secondary bandpass filter is designed such that its transmittance wavelength interval is limited by a short-wave edge and a long-wave edge and is adjusted to the primary bandpass filter in such a way that its edges shift over the required angle range only within the blocking bands of the primary bandpass filter.

Abstract: To reduce pumping time of a vacuum treatment chamber served by a transport arrangement in a transport chamber the vacuum treatment chamber is split into a workpiece treatment compartment and a pumping compartment in mutual free flow communication and arranged opposite each other with respect to a movement path of the transport arrangement serving the vacuum treatment chamber. The pumping compartment allows a pumping port to have a flow cross-section area that is freely selectable independently from the geometry of the treatment compartment.

Abstract: A vacuum treatment apparatus and method for manufacturing has a plurality of treatment chambers for treating workpieces, in particular silicon wafers, a transfer chamber attached to the treatment chambers communicating via respective openings and having handling zones located adjacent to each of the treatment chambers. A workpiece carrier is arranged within the transfer chamber and configured to transfer the workpieces between the handling zones, and one or more handlers for moving the workpieces between the handling zones and the treatment chambers. The transfer chamber is ring-shaped about an axis and the openings have opening substantially parallel thereto. This way, forces on the transfer chamber are redirected to a large support structure and thus, a cost-effective, light and still rigid mechanical construction can be achieved.

In desirable embodiments, a getter sublimation pump is also provided in the etching chamber as a source of getter material. Methods of etching in such a chamber are also disclosed.

Abstract: In a method for injection molding molten materials, especially plastic, in a mold that has a mold surface which comes into contact with the material, at least one coating on the mold surface and a temperature-control means for the mold surface, the mold surface is cooled by the temperature-control means so that the molten material solidifies at the interface with the coating and an injection-molded part can be removed from the form. During this process the molten material is brought into contact with the coating on the mold surface, the thickness of said coating being selected in coordination with the heat penetration coefficient of the coating material such that a specified 60° gloss level and/or color value L is obtained for the injection-molded part.

Abstract: A magnetron sputtering apparatus comprises, within a vacuum chamber (1), a substrate support (2) holding a substrate (3) with an upward-facing plane substrate surface (4) which is to be coated. The substrate (3) may be a disk of, e.g., 200 mm diameter. At a distance from a centre plane (5) two oblong targets (7a, 7b) are symmetrically arranged which are inclined towards the centre plane (5) so as to enclose an acute angle (?; ??) of between 8° and 35° with the plane defined by the substrate surface (4). Above the substrate surface (4) a collimator (13) with equidistant rectangular collimator plates is arranged. With this configuration high uniformity of the coating is achievable, in particular, if the distance of the collimator (13) from the substrate surface (4) is chosen as a multiple n of the extension of the collimator (13) perpendicular to the said surface, preferably with n equalling 1 or 2, for suppressing ripple.

Abstract: A silicon wafer-based solar cell with a two-layer antireflective coating (ARC) combines a 10-30 nm thick hydrogen containing passivation layer (e.g. SiXNY:H) with a top layer of Nb2O5 (or NbXOY in general) for optimal matching the refractive index of the ARC to cover materials having a refractive index of about 1.5 (e.g. glass or EVA, Ethylene Vinyl Acetate). The two-layer ARC can be deposited either by PECVD or by reactive sputtering (PVD) of a Si target with N2 and/or NH3, and the Nb2O5 layer is deposited by reactive sputtering of either a pure Nb target or a conductive Nb2Ox (x<5) target with O2.
