Abstract (en)

[origin: WO2007003255A1] The invention relates to a novel dispersible medium for etching doped tin oxide layers with a non-Newtonian flow behavior in order to etch surfaces during the production of displays and/or solar cells. Also disclosed is the use of said medium. The inventive medium is provided particularly in the form of particle-free compositions, by means of which selective fine structures can be etched without damaging or attacking adjacent surfaces.
