Abstract:
A stamper-forming electrode material contains Cu as its main ingredient and at least one other element, preferably Ag and/or Ti. It is preferred that the Ag content be 10.0 wt % or less and that the Ti content be 5.0 wt % or less. A stamper-forming thin film is made of this stamper-forming electrode material, whereby its corrosion resistance is improved to suppress damage to itself, and a high-quality stamper can hence be formed.

Electroplating articles and electroplating apparatus are also disclosed.
Abstract:
In the formation of microstructures, a preformed sheet of photoresist, such as polymethylmethacrylate (PMMA), which is strain free, may be milled down before or after adherence to a substrate to a desired thickness. The photoresist is patterned by exposure through a mask to radiation, such as X-rays, and developed using a developer to remove the photoresist material which has been rendered susceptible to the developer. Micrometal structures may be formed by electroplating metal into the areas from which the photoresist has been removed. The photoresist itself may form useful microstructures, and can be removed from the substrate by utilizing a release layer between the substrate and the preformed sheet which can be removed by a remover which does not affect the photoresist. Multiple layers of patterned photoresist can be built up to allow complex three dimensional microstructures to be formed.
Abstract:
The invention relates to a method for manufacturing a plurality of metal microstructures characterised in that said method includes the following steps: a) obtaining a conductive substrate or an insulating substrate covered with a conductive seeding layer; b) applying a layer of photosensitive resin to the conductive portion of the substrate surface; c) flattening the surface of the layer of photosensitive resin to a desired thickness and/or surface state; d) irradiating the layer of resin through a mask defining the contour of the desired microstructure; e) dissolving the non-polymerised areas of the photosensitive resin layer to expose the conductive surface of the substrate at parts; f) galvanically depositing at least one layer of a metal from said conductive layer such as to form a block that substantially reaches the top surface of the photosensitive resin; g) flattening the resin and the electroformed metal in order to make the resin and the electroformed blocks level and thus to form electroformed parts or microstructures; h) separating the resin layer and the electrodeposited layer from the substrate; and i) removing the layer of photosensitive resin from the structure obtained at the end of step g) in order to release the microstructures thus formed.

Disclosed is a method for producing micro-components in a simple manner consisting of the following steps: a magazine is produced from an electrically non-conductive moulding material encompassing at least one micro-component made from a chemically soluble material (micro-component of a first variety) on its side surfaces in positive fit; one side of the magazine and the micro-component of a first variety is provided with a coating or with a substrate of an electrically conductive material; the micro-component of the first variety is removed, the empty magazine is filled with a metal or a metal alloy to produce metal micro-components of a second variety and the coating or substrate is removed.
Abstract:
Die Erfindung betrifft ein Verfahren zum Herstellen einer Vielzahl plattenförmiger Mikrostrukturkörper aus Metall, bei dem durch wiederholtes Abformen eines die Mikrostrukturen aufweisenden Werkzeugs mit einer elektrisch isolierenden Abformmasse Negativformen der Mikrostrukturen erzeugt werden, die galvanisch mit einem Metall aufgefüllt werden, wonach die Negativformen entfernt werden, und bei dem elektrisch leitendes Material wieder lösbar auf die Mikrostrukturen des Werkzeugs aufgebracht und im Zuge des Abformens auf die Abformmasse übertragen wird. Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der gattungsgemäßen Art so zu gestalten, daß damit eine störungsfreie galvanische Auffüllung der Negativformen selbst bei sehr hohen Aspektverhältnissen und kleinsten charakteristischen, lateralen Abmessungen der Mikrostrukturen ermöglicht wird. Zur Lösung schlägt die vorliegende Erfindung vor, daß das elektrisch leitende Material auf die Stirnflächen (5a) der Mikrostrukturen (5) des Werkzeugs (4) aufgebracht wird, von wo es im Zuge des Abformens auf die diesen Stirnflächen (5a) gegenüberliegenden Formböden (10a) der Abformmasse (9) übertragen wird.
