Hi Jeffrey,
I had a similar Problem when I tried ro spin SU-8 onto a crosslinked and
hardbaked
layer of SU-8. It formed just single droplets on the surface of the
hardbaked SU-8.
A short (1 min) treatment with O2-Plasma fixed this problem.
Good luck

conductors on the SU-8.  Has anyone had any experience on this before?  It seems
that the AZ9260 keeps spinning off the SU-8 when I use 2100rpm for 60s.
