[labnetwork] Suggestions for interlocking mask aligners

[Leif Johansen]

Hello Vito,

At DTU Danchip we have two MA-6 aligners. On both tools we have interlocked the electrical signal for the solenoid controlling the CDA for the shutter. It works fine. If you want, we can mail you some pictures of how we did it.

Of course, if a user really wanted to cheat, he or she could perform all work before the exposure (i.e. mask load, wafer load and alignment) without logging in, and then only log in during exposure. In reality, we do not see such misuse.

Best regards,

Leif

Dear Colleagues,

I would appreciate hearing how you may have interlocked the mask aligners in your respective facilities. In our particular case we have a Suss-Microtec MA6 aligner and we are struggling to identify a parameter that can be interlocked without causing the system additional wear and tear. Any insights would be appreciated. Thank you.

Best regards,
Vito
