Abstract:
The disclosure relates generally to the field of processing substrates, for example comprising materials such as quartz, glass or silicon. The disclosure more particular relates to providing wet etch protection layers comprising boron and carbon and etching the substrate in a hydrogen fluoride aqueous solution. One or more of the boron and carbon containing films can have a thickness of at least 5, preferably 10 and, more preferably 30 nm. The method comprises wet etching the substrate in a hydrofluoric acid solution with a hydrogen fluoride concentration of at least 10 wt. % for at least 5 minutes.

Claim (Index 7):
The method of  claim 1 , further comprising maintaining a pressure of 0.1 Torr to 10 Torr within the reaction space during exposing the substrate to the vapor phase boron precursor.
