A method of forming a petterned substracte is provided. The method includes providing a substrate (300) having a structured surface region comprising one or more recessed features (310). The method includes disposing a first liquid (325) onto at least a portion of the structured surface region. The method includes contacting the first liquid with a second liquid (330). The method includes displacing the first liquid with the second liquid from at least a portion (315) of the structured surface region. The first liquid is selectively located in at least a portion of the one or more recessed features.
Abstract:
The present invention has a object to provide a surface ornamental structure of an article, easy for working and able to form a decorative pattern of an optional design and a high-grade feeling produced thanks to the metallic luster and, if necessary, to form a third dimensional decorative pattern. The present invention forms a metal-coated layer (2) by depositing a metal material with metallic luster on a surface of a base material (1). The metal-coated layer (2) is at least partly provided with a separation part (21), in which the based material (1) has its surface exposed to create an ornamental pattern thanks to a difference between the outer appearance of the base material (1) and the metallic luster of the remaining metal-coated layer (2). With the base material (1) and the metal-coated layer (2) exposed, respectively, each of their surfaces is coated with a clear-coating layer (3) made of synthetic resin material having transmittancy in order to protect the surface of the ornamental pattern (P).
Abstract:
An ink-jettable composition including a palladium aliphatic amine complex solvated in a liquid vehicle can be used in formation of electronic devices. The ink-jettable composition containing a palladium aliphatic amine complex can be jetted onto a substrate in a predetermined pattern. A second composition can also be applied to the substrate using ink-jet printing or other printing techniques, wherein the second composition is applied onto at least a portion of the predetermined pattern. The second composition can include a reducing agent which is capable of reducing the palladium aliphatic amine complex to palladium metal, typically upon the application of heat. The described ink-jettable palladium complex compositions can be stable over a wide range of conditions and allow for the formation electronic devices on a variety of substrates.
Abstract:
Nanolithographic deposition of metallic nanostructures using coated tips for use in microelectronics, catalysis, and diagnostics. AFM tips can be coated with metallic precursors and the precursors patterned on substrates. The patterned precursors can be converted to the metallic state with application of heat. High resolution and excellent alignment can be achieved.
Abstract:
Material can be deposited directly onto a substrate by using a fluid applicator such as an inkjet printer to apply at least two fluids which react to give the desired material for a range of applications. Thus, multiples of a printing mechanism are used to deposit materials as reagents that react together to form products. The materials may also be advantageously deposited from multiple inkjet heads to prepare a wide range of reaction scenarios in the form of user-defined patterns which may be sequences of differing layers and possibly to build up thicker layers. Thus, a PCB could be printed by the inkjet printer by simply printing the metal salt and the reducing agent directly, instead of two colours from a conventional inkjet printer for example. To print a three dimensional article, a pair of fluids which react to give a precipate can be used instead. Repeated passes can then build up a desired shape. The two processes could be combined to produce composite devices such as electrical components.
Abstract:
Method of forming a metallic structure (2) in a micro-machined recess that is provided in a surface of a semiconductor substrate (8). The method comprises positioning a protrusion (10) of an apparatus for depositing the metallic structure at least partly inside the recess, thus partly occupying the recess with the protrusion and defining in the recess a gap (14) along the protrusion. The method comprises driving a deposition fluid (20) through the gap in the recess along the protrusion. The method comprises growing in the gap the metallic structure by depositing metal ions contained by the deposition fluid. The method comprises moving the protrusion and the substrate relative to each other so that the protrusion, while being positioned in the recess, moves relative to the recess in a direction out of the recess, thus giving way for the growing of the metallic structure, and forming the metallic structure in the recess.
Abstract:
Semiconductor photovoltaic cells have surfaces that are textured for processing and photovoltaic reasons. The absorbing regions may have parallel grooves that reduce loss of solar energy that would otherwise be lost by reflection. One form of texturing has parallel grooves and ridges. The cell also includes regions of metallization for collecting the generated electrical carriers and conducting them away, which may be channels. The topography is considered during production, using a process that takes advantage of the topography to govern what locations upon will receive a specific processing, and which locations will not receive such a processing. Liquids are treated directly into zones of the cell. They migrate throughout a zone and act upon the locations contacted. They do not migrate to other zones, due to impediments to fluid flow that are features of the surface texture, such as edges, walls and ridges. Blocking liquid may also be deposited and migrate within a zone, to block or mask a subsequent activity, such as etching.
