Hi, Can anyone tell me what is an effective way to do lift-off with resist AZ5214E? I have tried the following process 1. Spin coat AZ5214E at 5000rpm on SiO2 or SU-8 wfr 2. Bake at 95'C for 1min 3. Expose at 74.1mJ/cm2 4. Develop in AZ Developer for 20s 5. Evaporate 10nm Cr & 300nm Gold at a rate of 0.07-0.09nm/s. 6. Lift-off using Acetone I have discovered that lifting off with acetone is more effectively done with ultrasonic treatment, but ultrasonic treatment is too harsh when the substrate is SU-8 as cracks will result. How about using AZ300 Resist stripper at 80-90'C or is there a better method? Thanks! Jeffrey
