  • SAFETY OPERATOR MANUAL TO OPERATE ON CMi WETBENCHES  (HERE)
  • Solvent chemistry: Do not breath unsafe NMP solvent vapor during lift-off processing.
  • Good working practice: When done, empty beakers in the dedicated waste bottles. Clean the work area of glass beakers, paper wipes, tweezers and make sure it is dry (no unidentified liquid).
  • Please immediately inform the CMi staff in case of problems with the equipment.

I. Introduction

The plade wet bench in Zone 1 is dedicated to wet processes involving photoresists with solvent chemistry only.

The processes that are allowed on this bench are:

  1. Photoresist stripping for metal lift-off on wafer batches (SVC-14 – DMSO)
  2. Photoresist stripping for metal lift-off on single wafers (SVC-14 – DMSO)
  3. General wafer cleaning (acetone, IPA, N2 drying)
  4. Back-side rinse on wafer batches after lithography steps (SRD)

Any other processes involving solvent chemistry, but not listed above, should be discussed with the equipment responsible.

Although no dangerous chemicals are used on this bench and safety dressing is not required, we encourage users to read and understand the wet bench safety manual.

II. Equipment description

Actual configuration:

  • Ultrasonic bath (US): SVC14
  • Tanks PT1, PT3, PT4: SVC14
