SU-8 will thermally cross-link if you bake it enough, and with some of the
lower-viscosity formulations you can spin films just a few microns thick.
You'll probably want to do a long, low-temperature pre-bake to remove as
much solvent as possible before bonding the two components together to
reduce defects.

Good luck.
