Abstract:
The invention relates to a method for producing micromechanical components (1), wherein a liquid starting material (2) which can be cured by means of irradiation is applied onto a substrate, and a partial volume (21) of the starting material is cured by means of a local irradiation process using a first radiation source in order to produce at least one three-dimensional structure. The three-dimensional structure delimits at least one closed cavity (10), in which at least one part of the liquid starting material (2) is enclosed. The invention further relates to a micromechanical component that contains a liquid starting material (2), which is partly cured by means of irradiation, and at least one cavity (10), in which the liquid starting material (2) is enclosed.
Abstract:
The invention relates to a method of making a three-dimensional structure in semiconductor material. A substrate (20) is provided having at least a surface comprising semiconductor material. Selected areas of the surface of the substrate are to a focused ion beam whereby the ions are implanted in the semiconductor material in said selected areas. Several layers of a material selected from the group consisting of mono-crystalline, poly-crystalline or amorphous semiconductor material, are deposited on the substrate surface and between depositions focused ion beam is used to expose the surface so as to define a three-dimensional structure. Material not part of the final structure (30) defined by the focused ion beam is etched away so as to provide a three-dimensional structure on said substrate (20).
Abstract:
The present invention provides a transfer substrate for transferring a metal wiring material to a transfer-receiving object, the transfer substrate comprising a substrate, at least one metal wiring material formed on the substrate and an underlying metal film formed between the substrate and the metal wiring material, wherein the metal wiring material is a molded article prepared by sintering, e.g., gold powder having a purity of 99.9% by weight or more and an average particle size of 0.01 µm to 1.0 µm and the underlying metal film is composed of a metal such as gold or an alloy. The transfer substrate is capable of transferring a metal wiring material to the transfer-receiving object even at a temperature for heating the transfer-receiving object of 80 to 300°C.
Abstract:
This disclosure provides implementations of high surface area stacked layered metallic structures, devices, apparatus, systems, and related methods. A plurality of stacked layers on a substrate may be manufactured from a plating bath including a first metal and a second metal. A modulated plating current can deposit alternate first metal layers and alloy layers, the alloy layers including the first metal and the second metal. Gaps between the alloy layers can be formed by selectively etching some portions of the first metal layers to define a stacked layered structure. Stacked layered structures may be useful in applications to form capacitors, inductors, catalytic reactors, heat transfer tubes, non-linear springs, filters, batteries, and heavy metal purifiers.
Abstract:
Disclosed is a method for producing a three-dimensional polymer-metal complex microstructure including forming a polymer structure by stereolithography using a photocurable resin having a reactive group X and dipping it in a liquid of a metal-containing nanoparticle having a reactive group X' which is bound to the reactive group X, thereby forming a metal-containing layer on the polymer structure through binding the reactive group X and the reactive group X'. According to this method, it is possible to produce a polymer-metal complex structure having a steric structure and to produce a three-dimensional polymer-metal complex microstructure which does not denature biomolecules in a metal complexation process.
