Abstract:
A method for forming a coating on a substrate using an atmospheric pressure plasma discharge. The method comprises introducing an atomized liquid and/or solid coating-forming material into an atmospheric pressure plasma discharge and/or an ionized gas stream resulting therefrom, and exposing the substrate to the atomized coating-forming material. The application also described a method for polymerizing a polymer forming material, and further to apparatus for forming a coating on a substrate.
Abstract:
Three fundamental and three derived aspects of the present invention are disclosed. The three fundamental aspects each disclose a process sequence that may be integrated in a full process. The first aspect, designated as “latent masking”, defines a mask in a persistent material like silicon oxide that is held abeyant after definition while intervening processing operations are performed. The latent oxide pattern is then used to mask an etch. The second aspect, designated as “simultaneous multi-level etching (SMILE)”, provides a process sequence wherein a first pattern may be given an advanced start relative to a second pattern in etching into an underlying material, such that the first pattern may be etched deeper, shallower, or to the same depth as the second pattern. The third aspect, designated as “delayed LOCOS”, provides a means of defining a contact hole pattern at one stage of a process, then using the defined pattern at a later stage to open the contact holes. The fourth aspect provides a process sequence that incorporates all three fundamental aspects to fabricate an integrated liquid chromatography (LC)/electrospray ionization (ESI) device. The fifth aspect provides a process sequence that incorporates two of the fundamental aspects to fabricate an ESI device. The sixth aspect provides a process sequence that incorporates two of the fundamental aspects to fabricate an LC device. The process improvements described provide increased manufacturing yield and design latitude in comparison to previously disclosed methods of fabrication.
Abstract:
Systems and methods for controlling, organizing, and viewing a plurality of electrostatic spray gun operating parameters from a centralized control panel are provided. In this regard, a master control panel is provided that can be shared by all the guns in the system. Each of the guns has an assigned gun control subpanel in the gun control area. Each subpanel includes a selector switch which can be used to monitor and control the gun associated with that subpanel on the master control panel. Each of the subpanels also has a limited display such as a bar graph which can be used to show the electrostatic performance of the guns. The subpanel displays are configured in a tight cluster so that the operator can easily simultaneously monitor the performance of all the guns in the system to identify any guns which are not performing properly.

Abstract:
A thin film deposition apparatus is used for applying thin films onto substrates, such as large panel displays, as well as integrated circuit devices, and includes a source of an ionized gas that is intermixed with an aerosol prior to deposition. The ionized gas causes the aerosol particles to take on an electrical charge. The aerosol containing the charged particles is concentrated in a virtual impactor and then provided to a shower head or orifice that is used for depositing the aerosol material onto the substrate. The shower head can be moved in a selected pattern to uniformly deposit aerosol particles as a thin film on the substrate.
Abstract:
A molten metal spray-depositing apparatus employs an ejection nozzle for receiving a molten metal stream and having a configuration for confining and imparting mechanically an angular momentum thereto which produces stream break-up into a metal particle spray when the stream becomes unconfined upon exiting the nozzle. There are stationary and rotating versions of the ejection nozzle. The stationary ejection nozzle has a flow channel with internal angular elements, such as spiral grooves, which engage the moving molten metal stream to impart angular momentum thereto as it passes through the channel. The rotating ejection nozzle may have internal elements within the flow channel, such as notches or serrations, which engage the moving molten stream and cause it to rotate with the nozzle as it passes through the channel. The two nozzles can also be combined to impart the angular momentum and accomplish melt stream break-up.
Abstract:
A molten metal gas-atomizing spray-depositing apparatus employs an asymmetrical gas-atomizing device for generating one-sided shear forces for breaking-up and atomizing a stream of molten metal into metal particles in a divergent spray pattern of higher mass density at an upstream leading peripheral portion of the spray pattern, relative to the direction of movement of a substrate, than either of a center region or downstream trailing peripheral region of the pattern.
Abstract:
The electrostatic conveyor consists of a duct having an inlet and an outlet, and apparatus for generating travelling, curvilinear, AC fields along the length of the duct. Charged particles, of conductive or non-conductive materials, under electrostatic forces, are exposed to unidirectional, centrifugal forces so that they are moved along the duct from the inlet to the outlet.
Abstract:
A TARGET OF A DIELECTRIC MATERIAL IS MOUNTED IN SPACED RELATION TO A CATHODE, WHICH IS ISOLATED FROM THE SPUTTERING CHAMBER AND THE ANODE IN THE SPUTTERING CHAMBER BY THE TARGET AND ITS MOUNTING STRUCTURE. RF ENERGY IS TRANSFERRED FROM THE CATHODE TO THE TARGET, WHICH HAS AT LEAST A PORTION PARALLEL TO THE ANODE, THROUGH THE SPACE BY A DIELECTRIC COOLANT, A LIQUID METAL, OR A METALLIC PASTE. WHEN EITHER THE METALLIC PASTE OR THE LIQUID METAL IS EMPLOYED, THE CATHODE IS COOLED BY CIRCULTING A COOLANT SUCH AS WATER THERETHROUGH.
Abstract:
The inventions disclosed by this application are for a cladding apparatus, a cladding head, and a method of cladding a relatively planar solid object such as a boiler waterwall. Cladding of non-horizontal surfaces is complicated by the effects of gravity as melted clad material trends to runoff the surface before the cladding material bonds to the appropriate location. The disclosed inventions overcome these limitations by controlling the relative angle of application by either rotating the workpiece or the cladding head through a pre-programmed sequence. Also presented in a compact design for a laser cladding head that facilitates such cladding by minimizing movement of the laser fiber and improves cladding speed over irregular shaped objects.
