摘要:
A cathode body for a rotating cylindrical magnetron wherein the magnetron provides a sputtering zone extending along the length of the cathode body and circumferentially along a relatively narrow region thereof. The cathode body includes an elongated tubular member having a target material at the outer surface thereof. A collar of electrically-conductive material is located at at least one end of the tubular member, and extends along the tubular member from that one end into the erosion zone. A sleeve of electrically-conductive material may extend circumferentially around the collar.
摘要:
A multilayer antireflection coating designed for deposition in in-line coating machines by DC reactive sputtering. About half of the total thickness of the coating may be formed from zinc oxide which has a high sputtering rate. Conductive transparent materials including aluminum doped zinc oxide, antimony doped tin oxide, cadmium tin oxide, and indium tin oxide may be included in the coating.

A mask arrangement is located between the cathode and substrate in an in-line sputtering system. The relative shape of the mask may be changed from outside the system. Thus, film thickness uniformity can be modified and controlled without interrupting the sputtering process.
摘要:
A multilayer, thin-film, broad-band, anti-reflection structure applicable to transparent substrates. The present invention makes use of the UV absorption properties of zinc oxide to provide UV rejection for wavelengths shorter than 380 nm, while providing anti-reflection properties in the visible region of the spectrum. The structure provides a reflection value less than 0.25% in the visible region of the spectrum, and blocks 99 percent of UV radiation below 380 nm.

摘要:
An optical analyzer measuring the reflectivity of a moving article in an in-line sputtering deposition system. The optical analyzer includes a light source which provides a light beam. Light is reflected from an optical coating of a moving article into a concentrator, which captures and directs the reflected light to a detector. The analyzer may be mounted in an evacuable chamber in which the end walls have openings to allow passage of the article.
摘要:
A method, apparatus and carrier for coating a CRT screen after assembly. The method and apparatus includes isolating a surface portion of the CRT to be coated from the remaining surface to prevent or minimize coating problems resulting from outgassing or difficulty in controlling coating process parameters and to isolate noncompatible components from the deposition environment.
摘要:
A magnetron cathode having a magnet housing which encloses a magnet array and has a cooling fluid passage therethrough. The magnet housing fills a significant portion of the cathode leaving a passage of relatively low cross-section for cooling fluid flow between the magnet housing and a cathode wall. The magnet housing may be hermetically sealed to prevent magnet corrosion and may be provided with rollers which engage the cathode wall to prevent magnet housing deformation due to magnetic forces.
摘要:
A rotatable magnetron cathode having at least one supported end adapted for attachment to a spindle. At least one dark space shield is attached to the cathode at a supported end to rotate therewith, and is electrically floating relative to the cathode. If the cathode is cantilever mounted, a floating cone end shield, facing away from the gas discharge and not overlapping the cylindrical cathode wall, is used at the free end.
