Process for manufacturing a micro-electrode
First Claim
1. A process for manufacturing an electrode (1) comprising creating a surface structure having at least one tip (3) or edge (4) on a substrate (2), forming a supply channel (9) in the substrate (2), such that the supply channel opens in close proximity to the tip (3) or edge (4) on a surface of the substrate, supplying a chemical through the supply channel (9), such that the chemical emerges at the tip (3) or edge (4), the chemical being one which upon irradiation with electromagnetic and/or particle radiation precipitates out an electrically conducting material, and irradiating the chemical in an area of the tip (3) or edge (4) with electromagnetic and/or particle radiation to precipitate out the electrically conducting material at the tip (3) or edge (4).

Abstract
In a process for manufacturing an electrode (1) on a substrate (2) using a conventional structuring process, an electrically conducting surface structure is created which has at least one tip (3) or edge (4). In the area of the tip (3) or edge (4), an electrode layer (5) is galvanized onto the substrate (2) and/or applied by electrostatic powder coating. Then, a surface area of the substrate (2), which surrounds the electrode layer (5) located on the tip (3) or edge (4), is converted into an insulating layer (8) by a chemical reaction. The electrode layer (5) can also be applied in a manner where, in the area of the tip (3) or edge (4), a chemical is released, which upon irradiation by electromagnetic and/or particle radiation, precipitates an electrically conducting material. This chemical is then impinged in the area of the tip (3) or edge (4) with optical radiation.

17. A process for manufacturing an electrode (1) comprising creating a surface structure having at least one tip (3) or edge (4) on a substrate, wherein the surface structure is produced from an electrically conducting material, applying at least one electrically conducting electrode layer (5) in the area of the tip (3) or edge (4) and also onto the substrate outside of the area of the tip (3) or edge (4) by galvanizing and/or applying an electrostatic powder coating thereon, and thereafter removing a portion of the electrically conducting material from the electrode layer (5) by etching until the electrode layer (5) is removed up to a residual area remaining in the area of the tip (3) or edge (4).
