Abstract:
The invention relates to a method for treating the surfaces of an electrically conducting substrate surface (2). According to said method, a tool (1) comprising an ion-conducting solid material is contacted with the substrate surface at least in some areas thereof, said tool being adapted to conduct the metal ions of the substrate surface and an electric potential (U) being applied thereto so that an electric potential gradient is applied between the substrate surface and the tool in such a manner that the tool removes metal ions from the substrate surface or deposits them onto the substrate surface.

Abstract:
Beschrieben wird ein Verfahren zur Oberflächenbehandlung einer elektrisch leitenden Substratoberfläche, bei dem ein festes Ionen leitendes Material in Form von ZrO 2 aufweisendes Werkzeug wenigstens bereichsweise in Kontakt mit der Substratoberfläche, die Kohlenstoff wie etwa Graphit und/oder Glaskohlenstoff enthält, gebracht wird, das als anionischer Ionenleiter ausgebildet ist und an das ein elektrisches Potenzial angelegt wird, so dass aus dem anionischen Ionenleiter Anionen austreten, die sich an der Substratoberfläche zu einer mit der Substratoberfläche reaktiven Verbindung umwandeln, und dass die reaktionsfähige Verbindung mit dem Graphit oder Glaskohlenstoff an der Substratoberfläche eine gasförmige Verbindung eingeht, wodurch die Substratoberfläche lokal abgetragen wird.

PROBLEM TO BE SOLVED: To provide the levelling method of a wafer covered with metal.SOLUTION: A tool 1 having a solid ion-conducting material is, at least partially, brought into contact with a base body surface 2 formed as a silicon wafer surface, the tool is formed as anionic conductive body, and a potential is applied to the tool, thereby, anions are discharged from the anionic conductive body, the anions are changed into a compound which reacts with the surface of silicon wafer on the surface of silicon wafer, the compound which can react with silicon isolates a gaseous compound on the surface of silicon wafer and, thereby, the surface of silicon wafer is locally removed.
Abstract:
PROBLEM TO BE SOLVED: To provide a method for giving a microstructure or nanostructure to the inside of the surface of a conductive substrate.SOLUTION: The method is used to treat the surface 2 of a conductive substrate. A tool 1 having solid ion conductive material is at least partly in contact with the surface 2 thereof, and it can conduct metal ion of the surface 2 and a potential gradient is generated between the surface 2 and the tool 1. Potential U is applied to the tool 1 so that the metal ion may be separated from the surface 2 through the tool 1 or be precipitated on the surface 2.
