Good photoresist choices for aqua regia (or another rhodium
etchant)

Dear MEMS Talk members,
Any suggestions on a good (positive) photoresist to hold off aqua regia? I
need it to last long enough to etch about 0.25 microns of rhodium. I am not
sure yet about the rhodium etch rate. Probably lower than gold.
Suggestions of an alternative method for etching rhodium are welcome!
Thanks for any help,
Jordan
