Etching Al2O3 can be done both chemically and by dry etching. We have not tested a chemical etch but a possibility could be to use a developer. This will be selective to most materials not containing Al. Do expect a slow and isotropic etch rate of about 1-2 nm/min. We have done some test of Al2O3 in dry etching. It has been mostly tested in the III-V ICP. Please see links below.

Etching Al2O3 can be done both chemically and by dry etching. We have not tested a chemical etch but a possibility could be to use a developer. This will be selective to most materials not containing Al. Do expect a slow and isotropic etch rate of about 1-2 nm/min. We have done some test of Al2O3 in dry etching. It has been mostly tested in the III-V ICP. Please see links below.
