Teos SiO2 Deposition Furnace (teos2)


Teos2 is the third furnace from the top of the Tylan2 bank.

SNF staff

Teos2 furnace allows LPCVD deposition of silicon dioxide, using tetraethyl orthosilicate (TEOS) which can provide a more conformal coating at lower temperature than tylanbpsg films. This is a six inch tube.

Steps to become a tool user

  1. Become a member of SNF.

  1. Study the relevant operating procedures:
  2. 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
  3. Contact the primary trainer: Alex Denton
