Patent ID: 7256467

Claim:
A MEMS device, comprising: a substrate; a movable microelectromechanical structure held on the substrate; a stop against which the micromechanical structure abuts at its maximum point of movement; wherein the stop and/or the movable microelectromechanical structure are coated with a layer comprising a siloxane material having a partially or fully fluorinated aromatic ring structure, said layer being formed by hydrolyzing a silane selected from the group consisting of a tetraalkoxysilane, a trialkoxysilane, a trichlorosilane, a dialkoxysilane, and a dichlorosilane, with a compound of the general formula R 1 R 2 R 4 MR 5 , wherein R 1 , R 2 and R 4 are independently an aryl, alkyl, alkenyl, epoxy or alkynyl group, wherein at least one of R 1 , R 2 and R 4 is fully or partially fluorinated, wherein M is selected from group 14 of the periodic table, and wherein R 5 is either an alkoxy group, OR 3 or a halogen, X, followed by depositing the material on the stop and/or the movable microelectromechanical structure.
