Simple lift off using ma N 440 - NanoLabStaff/nanolab GitHub Wiki

by Jonas M. Ribe ([email protected])


  1. Spin coat ma-N 440 (4.20μm)

     3000rpm for 30s
     Ramp: 3000rpm/s for 1s  
    
  2. Soft bake

     95°C for 5min 
    
  3. Exposure MA-6

     1300mJ/cm²
    
  4. Develop

     Ma-D 332s for ~3min (gently stirring)
     Rinse in DI for >30s
     Dry with N2(g)
    
  5. Deposit metal

  6. Acetone lift-off

     Rinse in acetone until resist with metal layer clears.
     Rinse in IPA.
     Dry with N2.
    

This is a simple lift-off process for when you don't need high resolution patterns. There should be no need for using an ultrasonic bath or elevated temperatures to clear the resist using acetone.
