We are about to evaluate new resist stripping chemistries.  I know I
will need one of the ME based strippers.  I was hoping those of you who
use Double Treated copper could share your experience.  I need a
chemical that will strip the dry film (aqueous) from the double treat
copper, leave the copper very clean and stains to a minimum and I want
to be able to treat the spent chemical without endangering my
operators.  I understand that in the new future we will not be able to
precipitate copper using the carbamate based chemicals and worry when
operators are cleaning the filter cake.

Thanks in advance
