Abstract:
An electrochemical etching cell for etching an etching body that is made at least superficially of silicon, comprising:at least two chambers filled at least partially with an electrolyte, one of which is provided with a first electrode that at least superficially has a first electrode material and the other of which is provided with a second electrode that at least superficially has a second electrode material, wherein one of the electrodes is connected as a cathode and the other of the electrodes is connected as an anode; wherein the etching body contacts at least region-wise with the electrolyte; and wherein the first electrode material and the second electrode material include an at least weakly conductive compound including at least one of silicon, carbon, nitrogen, oxygen, titanium, aluminum, boron, antimony, tungsten, cobalt, tellurium, germanium, molybdenum, gallium, arsenic and selenium.
