Abstract:
An apparatus and method for initiation and control of a sustained metal plasma and nano plasma (macroparticulate) deposition methods for preparing modified metal coatings are provided. The plasma deposition process can be tightly controlled by virtue of a device that incorporates a plasma arc initiator component and an internal power supply that is capable of controlling dwell time on the target and the size range of particles ejected in the plasma arc.
Abstract:
A plasma vapor deposition method for producing highly reflective and adherent metal or metal alloy decorative coatings on articles such as automotive fixtures is described. The improved coatings are particularly applicable to chrome based coatings on automobile fixtures and accessories, including wheels, hubcaps, bumpers and door handles. The method also provides plated metal coatings such as gold, platinum and silver for jewelry and industrial tools.
Abstract:
A plasma chamber in a semiconductor fabrication system uses a two step process to sputter deposit material onto a substrate. The first step provides a power ratio of RF power to DC power optimized to increase uniformity of deposition of material onto a workpiece from a first target. A second step involves applying little to no DC power to the target, while an RF power is coupled into a plasma generation region to sputter material from a second target onto the workpiece. It has been found that material from the second target provides greater sidewall coverage of channels located on the workpiece, as well as increasing the uniformity of the deposit on the surface of the workpiece.
Abstract:
Forming an alkali (earth) metal layer of a photoelectric conversion device with high productivity. In manufacturing a photoelectric conversion device having a photoelectric conversion layer that includes, as a major component, a compound semiconductor having a chalcopyrite structure formed of a group Ib element, a group IIIb element, and a group VIb element, an alkali (earth) metal supply layer is formed by a sputtering method using a semi-conductive or conductive target that includes one or more types of alkali metals and/or alkali earth metals. Alternatively, an alkali (earth) metal supply layer is formed by a reactive sputtering method in the presence of oxygen and/or nitrogen using a semi-conductive or conductive target that includes one or more types of alkali metals and/or alkali earth metals.
Abstract:
Изобретение относится к обработке материалов в вакууме методом локализованного высоковольтного тлеющего разряда, а именно, к распылению и направленному переносу наноразмерных частиц электропроводных материалов. Способ предназначен для приготовления высококонцентрированных суспензий наноразмерных электропроводных материалов на основе водорастворимых и не водорастворимых жидкостей. Способ реализуется с помощью устройства, которое состоит из системы распыления материала катода и размещенной в вакуумной камере емкости с обрабатываемой жидкостью. Техническим результатом изобретения является возможность создания высококонцентрированных однородных суспензий на основе широкого спектра жидкостей и расплавов.
Abstract:
A liquid electrode tip has a housing with a top, a bottom and at least one peripheral side wall. The housing has a liquid inlet and a liquid outlet. The liquid outlet is located at the top of the housing. A solution reservoir is positioned within the housing. The solution reservoir has a solution inlet in fluid communication with the liquid inlet and a solution outlet in fluid communication with the liquid outlet. A conductor is positioned within the housing with at least a portion of the conductor being submerged by a liquid in the solution reservoir. A staging area at the top of the housing is provided into which the liquid from the solution reservoir flows from the liquid outlet.
