An optical storage medium having at least two information layers is provided, wherein a first information layer is in the form of a dichroic filter that is reflective at a first selected wavelength and transmissive at a second selected wavelength. The dichroic filter has a laminate structure that includes at least a metallic layer and a dielectric layer, wherein the total thickness of the dichroic filter is about or less than 100 nm. A second information layer that is reflective at the second wavelength is disposed behind and spaced from the dichroic filter. This construction permits a first incident light beam at the first wavelength to be reflected from the dichroic filter, to produce a first reflected beam carrying information recorded in that layer. A second incident light beam at the second wavelength can be transmitted through the dichroic filter and reflected from the second information layer to produce a second reflected beam that passes through the dichroic filter, carrying information recorded in the second information layer.

An etching chamber is equipped with an actively-cooled element preferentially adsorbs volatile compounds that are evolved from a polymeric layer of a wafer during etching, which compounds will act as contaminants if re-deposited on the wafer, for example on exposed metal contact portions where they may interfere with subsequent deposition of metal contact layers. 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.

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 (β; −β) 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.

An exhaust opening of a process chamber (12) contained in a vacuum chamber (11) is connected to an exhaust line (13) by a connector comprising a bellows (03) with one end which is connected to the exhaust line (13) fixed to a housing and its opposite end carrying a coupling tube (02) for connecting to a coupling ring (01) which surrounds the exhaust opening, the coupling tube (02) being elastically biased towards the same. The coupling tube (02) can be moved between a connected state where it is in contact with the coupling ring (01) and a disconnected state by an actuator reciprocatable in an axial direction perpendicular to the exhaust opening. To enable a gas-tight connection with the process chamber (12) the coupling tube (02) has lateral play such that it can align with the coupling ring (01) when a conical surface of the coupling tube (02) contacts a complementary conical surface on the coupling ring (01) in the connected state. The actuator comprises two rods (04) which extend through drill holes of an outward extending holding ring (05) of the coupling tube (02) and interact with the same in such a way that the lateral position of the coupling tube (02) is fixed in the disconnected state.

摘要:
Throughput of manufacturing thin-film solar panels by inline technique is made substantially independent from the time extent of different surface treatment steps by accordingly subdividing treatment steps in sub-steps performed in inline subsequent treatment stations. Treatment duration in each of the subsequent treatment stations is equal (τ).
