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 19):
A device comprising:\n a boron and carbon-comprising wet etch protection layer on a substrate, wherein the wet etch protection layer has a thickness of at least 5 nm, and wherein the wet etch protection layer has etch resistance sufficient to protect the substrate from exposure to a hydrofluoric solution with a hydrogen fluoride concentration of at least 10 wt. % for at least 5 minutes.
