RENA monoTEX® - moderating and wetting agent

monoTEX®

IPA-free alkaline texturing for mono Si-wafers

monoTEX^® is the best-in-class type of moderating and wetting agent for alkaline texturing. Unlike the common texturing agent IPA, RENA monoTEX^® is non-flamable and operating at temperatures far below the boiling point of its components. It behaves almost linear towards temperature and alkali concentration changes and allows tuning the size of the pyramids by adjusting process parameters.
