Abstract (en)

[origin: WO2021165308A1] According to the invention, when treating substrates with a treatment medium containing at least one chemical effective for treatment, for example when removing a masking layer (101) from a semiconductor substrate (110) by etching, the treatment medium is heated to a temperature effective for treatment only immediately prior to apply to the substrate (110), the treatment medium being at the optimum temperature for treatment when it impinges on the substrate. Thus, a short treatment time, low, thermally induced decomposition losses of chemical and a saving of treatment medium are achieved.
