Wenlin, If you use google and enter stiction, you will get a number of references to stiction and how to cure it. One of the items mentioned is the coating used by T.I. for their D.M.D. Distortable Mirror Devices. My company developed the deposition units for T.I. for this process. We also develop and manufacture a number of plasma units for the Semiconductor and M.E.M.'s world. If I can help please contact me by email or phone 408 954 8353.

It has been observed that after certain cycles of operation, stiction of the beam to substrate occurs. I'm wondering if there are researches done on the mechanism of the stiction and how it can be avoided. Any information will be appreciated.
