Gold Etchant?

Hi Labmembers,

Does anyone know if the gold etchant at CIS also etches lead (Pb)? I had a thin lead film on top of a patterned gold layer, and tried to lift off with gold etch, but the lead film seems to be gone after using the gold etchant... I'd appreciate it if anyone has an idea.

Thanks,
Takane
