FePt Alloy Etching

I have a process which requires metal etching in a particular pattern (produced by photomask). I was wondering would this be possible to do with dry etching on dryteks at SNF? or we need to do a wet etching, but in case of wet etching would the photoresist survive the wet-etch?
The metal I want to etch is 100nm Fe-Pt (50:50 approx) Alloy with 40 Angstroms of carbon as capping layer.
Thanks a lot for your help.
