does anyone have a small quantity of cu-wet-etchant to spare? It's
fairly cheap i was told so i can return it in a few weeks, but i need to
do a quick test tomorrow or sometimes this weekend.
i need to etch Cu on blue tape with 3612 resist as a protective covering
after litho. Nitric Acid etches Cu but will also etch away the resist.
sputtering in mrc is an alternative too, but wet-etch would be cleaner.
Thank you.
