I do not know about Al epoxy, but when I've needed to remove silver expoxy
from a chip, I've found that an HNO3-based silver etch took care of it
fairly well without damaging my structures. Of course, you'd have to use an
etch that didn't attack (or attacked at a much lower rate) whatever else is
on your wafer.
