Hi All Au etchant users:
Please pour the used Au etchant into the Au- waste container, don't
pour it back into the fresh Au etchant bottle.
A labmember used the Au-etch, and it looks like the Au etchant has been
contaminated with resist.
Try to minimize the amount of chemical you are going to use. Please
contact me if you need to use a larger amount, we could set up a used Au
etchant bottle for you.
