摘要:
A method for forming a flow director on a component having a wall includes depositing at least one layer on the wall of the component. The deposition includes shaping the layer in accordance with a predetermined shape to form the flow director. An exemplary component is a turbine component with a wall having a cold surface and a hot surface. At least one film-cooling hole extends through the wall, for flowing a coolant from the cold surface to the hot surface, and defines an exit site in the hot surface of the wall. An exemplary deposition process includes delivering a mixture through a nozzle onto the wall to form the layer, where the mixture includes a powder dispersed in a liquid medium, displacing the nozzle relative to the wall and controlling the movement of the nozzle relative to the wall to form the layer in accordance with the predetermined shape.

Disclosed herein are a biaxially textured pure metal or alloy layer deposited by electroplating process on the surface of a single-crystalline or quasi-single-crystalline metal substrate, and a method for manufacturing the biaxially textured pure metal or alloy layer. Specifically, the biaxially textured pure metal or alloy layer is deposited by electroplating process on the surface of a pure metal or alloy substrate having single-crystalline or quasi-single-crystalline orientation. The biaxially textured pure metal or alloy layer has a misorientation on the c-axis of 4null or less and a misorientation on the plane formed by the a-axis and b-axis of 5.2null or less in which the misorientation on the c-axis is determined by a Full Width at Half Maximum of peaks on the null-rocking curve and the misorientation on the plane formed by the a-axis and b-axis is determined by a Full Width at Half Maximum of peaks on the null-scan. The biaxially textured pure metal and alloy layers can be manufactured simply by electroplating process without the need for additional processes. In addition, the biaxially textured layers fabricated according to method in the present invention exhibit excellent texture compared to those manufactured through conventional processes, and thus can be used as metal substrates for superconducting wires and thin film magnetic materials. Accordingly, they are expected to greatly contribute to the development of related industries.
摘要:
The present invention provides a method for forming a conductive film with uniform properties on a wafer surface that has features or cavities. During the process, the workpiece is rotated and laterally moved while an electrodeposition solution is delivered onto the wafer surface at a predetermined flow rate, and a potential difference is applied between the workpiece surface and the electrode. The workpiece is rotated about an axis at predetermined revolutions per minute so that an edge region of the workpiece has a first predetermined linear velocity due to the rotation. The workpiece has a second predetermined linear velocity due to the lateral motion. The second predetermined velocity may be larger than the first predetermined velocity. Further, the wafer may not be rotated.

A substrate processing apparatus fills a metal such as copper or the like in fine interconnection patterns or trenches defined in a semiconductor substrate. The substrate processing apparatus has a loading/unloading unit for placing a substrate cassette to allow a substrate to be loaded and unloaded, a substrate treating unit for treating a substrate, and a transfer robot for transferring a substrate between the loading/unloading unit and the substrate treating unit. The loading/unloading unit, the substrate treating unit, and the transfer robot are installed in a single facility. The loading/unloading unit has a rotary table which is horizontally rotatable for positioning the substrate cassette in a position to detect the substrate cassette placed in the loading/unloading unit and to remove the substrate from the substrate cassette with the transfer robot.

A method and apparatus for processing a microelectronic workpiece. The apparatus can include a vessel configured to receive a processing fluid and can further include a support member having a contacting portion configured to carry the microelectronic workpiece at least proximate to the vessel. The apparatus can further include a heater positioned at least proximate to at least one of the vessel and the support member to heat at least a portion of the support member. Alternatively, the heater can be positioned to heat at least a portion of the microelectronic workpiece in addition to, or in lieu of heating the support member.
摘要:
An apparatus and method for treating a substrate to deposit, clean or etch material on a substrate uses a first horizontal chuck to which a plurality of substrates is attached and electrically charged. Spaced closely to the first horizontal chuck is a coextensive horizontal second chuck which receives and showers reaction solution over all portions of each substrate. During the reaction process, both chucks are substantially submerged in reaction solution within a tank. At least one of the chucks is attached and controllable from a control arm. At least one of the chucks is rotated about a vertical axis at a slow speed during the reaction process. The axes of rotation of the two chucks may be coincident, or the axes may be offset from each other, and/or one or both axes may be offset from the chuck centerpoint(s). One of the chucks may also be periodically moved in a vertical direction relative to the other chuck.

A method for immersing a substrate into a processing solution. The method includes connecting a power supply between a conductive layer on the substrate and an electrode positioned in the processing solution, immersing the substrate into the processing solution, and applying an electrical bias to the conductive layer during the immersion.
摘要:
An electrochemical method for generating both mesoporous metal and metal oxide films from dilute surfactant solutions by utilizing self assembly of surfactant-inorganic aggregates in the electric field of the solid-liquid interface at an electrode to specifically direct the morphology of the film. The surface of the working electrode serves as a solid-liquid interface in a plating solution containing surfactant and inorganic ions and salts.

A method for producing an array of oriented nanofibers that involves forming a solution that includes at least one electroactive species. An electrode substrate is brought into contact with the solution. A current density is applied to the electrode substrate that includes at least a first step of applying a first substantially constant current density for a first time period and a second step of applying a second substantially constant current density for a second time period. The first and second time periods are of sufficient duration to electrically deposit on the electrode substrate an array of oriented nanofibers produced from the electroactive species. Also disclosed are films that include arrays or networks of oriented nanofibers and a method for amperometrically detecting or measuring at least one analyte in a sample.
