Maria: It seemed to work just fine. Here is an SEM of SU-8 at 5 microns thickness without cross linked bake after a DRIE etch and prior to resist removal. As you can see the resist has been battered by the rie effects but after a 50 micron silicon etch using SF6 + O2 chemistry it still has coverage.
