I am learning to use the 1510 Ultrasonic cleaner to clean photoresist residue after lift-off with 3000PY resist and after patterning with 1813 resist. I understand that the wafers have to be placed inside a beaker and the beaker inside a different solution inside the cleaner. I would like to know what solutions are used to clean either 3000PY or 1813 (solution inside beaker) and what solution goes inside the cleaner.
