The Solvent Bench 83 is for working with solvents, stripping resist, and cleaning wafers. It is considered a non CMOS-clean bench, so wafers with metal are allowed in the bench. It is intended for use with all sized wafers and materials.

Warning Warning: If you use this bench for stripping photoresist you will not be allowed to return to CMOS clean or semi-clean tools


In both the Cleanroom and the Robin Lab, the LNF has updated the personal protective equipment policy at Solvent Benches. In addition to the mandatory chemical safety glasses, face shield are now recommended to be worn when possibility exists for eye contact due to splashing/spraying liquid.

Hardware details

This bench contains a dedicated PRS 2000 bath, a DI Rinse tank, and an aspirators on this bench that goes to solvent waste carboy.


Proper PPE for this bench are Trionic or Neoprene gloves and safety glasses. If the possibility exists for splashing/ spraying, please wear a faceshield
Warning Warning: You must use the buddy system for all chemical processing. No processing if you are alone in the lab. If the yellow warning lights are on it means that there are 2 or 1 people in the lab.

Working with chemicals can be very dangerous. Many solvents are very carcinogenic so avoid contact and breathing the vapors. To minimize the chance of accident, make sure you always:

  • Wear personal protective equipment. Required PPE at this bench are safety glasses and Trionic or Neoprene gloves.
  • LNF Glove Policy
  • Know the properties and hazards of chemicals you are working with. If you don’t know, find out by reading about them or asking staff.
  • Plan the details of your process. Before you start working, plan what quantities of chemicals and sample carriers you will use. Plan how you will rinse your sample and what you will do with any waste generated. Make sure you know how the controllers work.
  • Do not use this bench without proper training.
  • Solvent Aspirator: Only solvents can be disposed of using this aspirator. Do not aspirate water with this aspirator.
    • Water waste goes in the tank on the front left side of the bench. Rinse all labware and pour the water waste into this. Do NOT aspirate
