- Silicon surface by applying the solution textured and / or polished (for example, smoothed).
- the solution can react chemically with the silicon surface, for example with silicon atoms of the silicon surface.
- silicon can be removed from the silicon surface, wherein a texture and / or a polish can be produced by removing silicon.
- providing the solution may include providing the source of chlorine by means of a chloride and a plurality of oxidants.
- a mixture of different oxidants may include providing the source of chlorine by means of a chloride and a plurality of oxidants.
- the solution may be as follows
- Ammonium chloride (NH 4 C1) may be added.
- a method for producing textures or polishes on the surface of monocrystalline silicon wafers may or may be provided by subjecting the surface to an etching process, characterized in that an aqueous mixture of hydrofluoric acid (HF), hydrochloric acid (HCl), and an oxidizing agent is used as the etching solution.
- HF hydrofluoric acid
- HCl hydrochloric acid
- oxidizing agent an oxidizing agent
- Pre-textured or pre-polished silicon (100) wafers Pre-textured or pre-polished silicon (100) wafers.
- the application of the solution to the silicon surface can take place by means of a bath (eg an etching bath),
- the schematic removal rate composition diagram 101 illustrates the removal rates as well as the obtained
- This surface morphology corresponds to applying a solution according to the composition (k) in FIG. 1, wherein a pyramidal structure 204 can be generated.
