I have used FeCl3 to etch InP anisotropically in the past. The mask was
the plated gold pad. The collimated UV light was used to guide the
etching. Proper agitation of FeCl3, or the sample rotation in my case,
Hope it helps.

I'm hoping to etch patterns into/through copper, nickel, and/or aluminum
foils using an aqueous solution of FeCl3. I was wondering if anybody
any experience etching any metals with FeCl3, and which masks work for
process. Any help would be greatly appreciated! Thanks,
