I. Introduction
The Arias Lift-off wet bench in Zone 12 is dedicated to long-duration wet processes involving photoresists with solvent chemistry only.
It is dedicated for lifting off deposited material on wafers and chips (Remover 1165 – NMP or SVC-14 – DMSO)
Any other processes involving solvent chemistry should be discussed with the equipment responsibles.
Although no extremely 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.
In case of long processes, unnatended beakers should be clearly labelled with username, solvent type and expected return date/time.
