Abstract (en)

[origin: WO2014135450A1] The invention relates to a method for producing a soot sensor, comprising the method steps of applying a contiguous metal layer to an electrically insulating substrate (1); structuring the metal coating with a laser beam by vaporizing areas of the metal layer, wherein at least two interleaved contiguous electrically conductive structures (2, 3) are produced and the electrically conductive structures (2, 3) are spatially separated from one another with the laser beam and are electrically insulated from one another in such a manner that the conductive structures (2, 3) substantially run beside one another and close to one another in this area based on the total length thereof. The invention also relates to a soot sensor produced using a method according to one of the preceding claims, in which the soot sensor has an electrically insulating substrate (1) and at least two contiguous electrically conductive structures (2, 3), which are spatially separate from one another and are interleaved, as structured metal layers, wherein the intermediate space between the conductive structures (2, 3) is burned free with a laser, the intermediate space is preferably smaller than 50 µm at least in certain areas, and contact is made with the heating coils using widened conduction layers (14).
