Setup time for this process is about 5 minutes. This process takes about 15 minutes to
complete.
Solvents can clean oils and organic residues that appear on glass surfaces. Unfortunately,
solvents themselves (especially acetone) leave their own residues. This is why a twosolvent
method is used.
Pour the acetone into a glass container. Pour the methanol in a separate container. Place
the acetone container on to a hot plate to warm up (do not exceed 55 deg C). Place the
silicon wafer in the warm acetone bath for 10 minutes. Remove and place in methanol for
2-5 minutes. Remove and rinse in DI water (DI water rinse is optional). Blow nitrogen. If
the solvents are clean and you intend to use them again, store in appropriately labeled
containers with name date and contents. Do not pour any solvents down the drain.
