There is a paper on Jpn.J.Appl.Phys. Vol. 32 (1993) pp. L1642-1644,
dicribing the Photoresit-Assisted release. It may be helpful to you.
good luck.

Subject: [mems-talk] Wet etching


Dear MEMS experts,
We are looking to make wet-ecthing of a SiO2 sacrificial layer under a
freestanding layer.
The problem is stiction.
I know that we have to use SCO2 in order to improve the reproductibility
of the process but what can we do in order to obtain any layers without
sticting only using usual techniques?
After etching, we wash the sample in water and  in propanol solution.
Our wafer is in Silicon.
Thanks for information
