Abstract:
Es wird ein Verfahren zum Verbinden zweier Fügeflächen, insbesondere in der Halbleitertechnik vorgeschlagen, bei dem mindestens eine Fügefläche durch Abscheiden einer Schicht bestehend aus 20 bis 40% Gold und 80 bis 60% Silber auf einen Träger und selektives Entfernen des Silbers aus der abgeschiedenen Schicht zur Erzeugung einer nanoporösen Goldschicht als Fügefläche hergestellt wird. Die Fügefläche mit nanoporöser Goldschicht und eine weitere Fügefläche werden übereinander angeordnet und zusammengepresst.
Abstract:
The invention provides method for preparing a conductive device comprising the steps of: (a) providing a non-conductive substrate layer; (b) modifying the surface of the non-conductive substrate layer by means of a laser beam treatment; (c) applying a pattern of an ink on a surface of the substrate layer, which ink comprises a first metal; (d) depositing a second metal on the ink pattern obtained in step (c); and (e) applying a third metal on the second metal by means of electrodeposition. The invention further provides a conductive device obtainable by said method.
Abstract:
A layer of transparent conductive a material is disposed on a surface of a substrate. Further layers of conductive material are deposited on the layer of transparent conductive material or on an opposite surface of the substrate. The layers are selectively etched to yield a layout of pads for mounting electrical components and conductive traces forming an electrical circuit.

Abstract:
Disclosed is a process for applying a kinetic spray coating of powder particles onto a substrate (86, 92, 116) covered in a plastic-type material (82, 84, 90, 112, 114) without first removing the plastic-type material (82, 84, 90, 112, 114). In one use of the process a mask (118, 122) is used to enable a single kinetic spray pass to both remove the plastic covering (82, 112) and bind particles having average nominal diameters of from 60 to 250 microns to the underlying substrate (86, 92, 116). In another use of the process the particles have an average nominal diameter of from 250 to 1400 microns and the use of a mask (118, 122) is optional because the particles can penetrate the plastic material (82, 84, 112, 114) and bind directly to the substrate (86, 92, 116). The process finds special use in forming electrical connections or solderable pads anywhere along the length of a flexible circuit.
Abstract:
The invention relates to a support for electrical circuit elements that, for electrically connecting circuit elements by soldering, bonding or gluing, is comprised of a structured base body or is coated with structures consisting of easily oxidizing metals that have a multilayer, electrically conductive covering, which is inert on the outer surface, prevents a migration of the easily oxidizing metals, and has good soldering, bonding or adhering properties. The covering has the following composition: a) a first single ply or multiply layer that serves as an adhesive/barrier layer; b) a second single ply or multiply layer that serves as a functional layer for soldering, bonding or gluing, and; c) a third single ply or multiply layer, which is placed on the outer surface of the covering and which has inert properties and a high surface energy.
