I saw Cu wafers lying around next to the tool and I am not very sure that
it got etched in the STS etcher 1.
I did noticed on the wafer etched in stsetch1 with Cu on the back side.

Please do know that Cu inside the clean or semi clean tool is *STRICTLY NOT

Please make sure that you are not etching any wafers which has Cu on them.
If you need help,please ask staff for other tools.

Thank you.
