Plasma Therm Versaline LL ICP Dielectric Etcher (PT-Ox)
Overview
PlasmaTherm Oxide Etcher (PT-OX) is an ICP (Inductively Coupled Plasma) etch system configured for the etching of oxide and deep glass/quartz , using F chemistry, located in the SNF Cleanroom. It is a single wafer etcher for 4 or 6 inch wafers, with a load lock, and is in the “flexible” cleanliness group in SNF.

Steps to become a tool user
-
Become a member of SNF.
- Study the relevant operating procedures:
- Online training and completing the quiz is required. See Online Course for general information about the online training. Go to Online Nano Course Login to log in directly to the course.Go to "nano@stanford" and then to the "PlasmaTherm Etchers Guide" section for watching the video and taking the quiz. For optional overview of plasma etching and how to choose an etcher, go to the "Dry Etching" Section for the three videos on plasma etching principles and "Choosing a Dry Etching Process" section for guidelines for choosing the right equipment.
- Shadowing is required. Contact a qualified lab member of the tool to arrange to ‘shadow’. It would be best to find someone who has used the system often. If you don’t know of anyone, you may check reservations or history to find a qualified user. We recommend that you be with the lab member for the full time while operating the tool and ask lots of questions during the shadowing. You may have to shadow a qualified user more than one time to be comfortable with the tool. Please follow the instructions on this form: Shadowing at SNF
