Hi,
Does anyone know the (approximate) etch rate of Cu in BHF ?
I am using BHF to remove a copper oxide layer generated on my structures during
processing. I expect the Cu etch rate to be very small, though I would like to
have this confirmed.
The Cu on my wafers have been deposited by means of MOCVD. Perhaps this is
relevant to the question above ?
Thanks,
Frank
