Aluminium Oxide (Al2O3) Ion Beam Etch (IBE)

Al2O3 may be etched using the Reactive Ion Beam Etch (RIBE) process technique.

Process features

  • Process gases: Ar, CHF3, O2
  • Al2O3 etch with rotation and adjustable tilt

 

 

 

 

Summary performance data

Chamber base pressurea <3e-7 Torr
Load lock base pressureb   <1e-5 Torr

a. After 12 hours bake out at 80°C
b. Load lock pumps down to 6E-5Torr in less than three minutes. It takes less than five minutes from sample loading i.e. from the load lock to process platen with load lock pump down sequence.
