Abstract:
A device and method utilizes interconnecting layers separated by an insulating layer. A layered structure comprises a first and a second layer of electrically conductive material, and a third layer of electrically insulating material between them. A via trench is fabricated that extends from the second layer through the third layer into the first layer, a surface on the first layer of electrically conductive material forming a bottom surface of the via trench. An ink-jetting set-up for a mixture of liquid carrier and nanoparticles of conductive material is formed, and a specific process period is determined. Capillary flow of nanoparticles to peripheral edges of an ink-jetted blob of said mixture is induced. The mixture is ink-jetted into a blob on the via trench; the layered structure is heated to evaporate the liquid carrier. The interconnection element is higher at a certain point than between opposing side walls.

Abstract:
The present invention relates to a method for manufacturing a module type microfluidic chip comprising: (a) printing electrode patterns on a substrate using a conductive ink and inkjet printing; (b) cutting the printed electrode patterns; and (c) assembling the cut electrode patterns to manufacture the module type microfluidic paper chip. Unlike the traditional method for manufacturing printed circuit substrate using a patterning agent or device, the method of the present invention only incorporates a simple printing process using an inkjet printer, and thus patterning can be simplified and various types of chips can be manufactured depending on the assembly type of electrode patterns. Accordingly, inexpensive, economical, and highly utilizable microfluidic chips can be provided using the method of the present invention.
Abstract:
A method of producing a three-dimensional structure contains the steps of: arranging a substrate close to a tip of a needle-shaped fluid-ejection body having a fine diameter supplied with a solution, ejecting a fluid droplet having an ultra-fine diameter toward a surface of the substrate by applying a voltage having a prescribed waveform to the needle-shaped fluid-ejection body, making the droplet fly and land on the substrate, and solidifying the droplet after the fluid droplet is landed on the substrate; further a three-dimensional structure has a fine diameter comprises droplets having an ultra-fine particle diameter, wherein the structure is grown by solidifying the droplets and stacking the solidified droplets.
Abstract:
A switch and a relay include a contact with a smooth contacting surface. A side surface of a fixed contact faces a side surface of a movable contact. The fixed contact has an insulating layer and a base layer stacked on a fixed contact substrate, and a first conductive layer formed thereon through electrolytic plating. The side surface of the first conductive layer that faces the movable contact becomes the fixed contact (contacting surface). The movable contact has an insulating layer and a base layer stacked on the movable contact substrate, and a movable contact formed thereon through electrolytic plating. A side surface of a second conductive layer that faces the fixed contact becomes the movable contact (contacting surface). The fixed contact and the movable contact have surfaces that contact the side surfaces of the mold portion when growing the first and second conductive layers through electrolytic plating.
