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:
An antireflection coating for a substrate including four layers and having optimized photopic reflectance and optimized for deposition by sputtering. The first layer (the layer farthest from the substrate) has a refractive index less than the refractive index of the substrate and a thickness of about one-quarter wavelength. The second layer (the layer adjacent the first layer) has an refractive index greater than about 2.2 and a thickness of about a half wavelength. The third layer has refractive index less than that of the second layer. The fourth layer (the layer adjacent the substrate) has a refractive index less than about 2.0 and greater than that of the third layer. The combined thickness of the third and fourth layers is less than about a quarter wavelength. The first and third layers may include silicon dioxide. The second layer may include titanium dioxide or niobium oxide. The fourth layer may include indium oxide, tin oxide, indium tin oxide, or zinc oxide.
摘要:
A method and apparatus for cleaning a substrate in preparation for thin film coating. The invention involves cleaning the substrate in a cleaning chamber under controlled conditions by a blast of carbon dioxide pellets suspended in and transported by a compressed gas medium.
摘要:
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 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 coating for an article comprising layers of nitrides of certain transition metals to provide an electrically-conductive, light-attenuating, antireflection surface.
摘要:
A system for evaluating the reflectance of an object (e.g., a CRT) that is coated with an anti-reflective coating material is disclosed. The quality and/or uniformity of the coating is evaluated by a reflectometer. The reflectometer is positioned relative to the object by non-contact sensors. Reflectance data gathered by the reflectometer is analyzed to determine to what extent the actual coating differs from the optimal (i.e., ideal) coating. A feedback system modifies the coating process for subsequent objects in an attempt to fine-tune the coating process and achieve optimal anti-reflective coatings for later objects passing through the system.
