Abstract
Abstract It is possible to use an oriented monolayer to limit the Van der Waals forces between two elements by passivation. An oriented monolayer (34) is formed upon the landing electrode (10) of a spatial light modulator element. When the element is activated and deflects to come in contact with the landing electrode, the oriented monolayer decreases the Van der Waals forces and prevents the element from sticking to the electrode.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
142 words
An electronic device comprising: a) at least one address electrode in a substrate; b) at least one landing electrode in said substrate adjacent said address electrode; c) a support layer formed upon said substrate such that at least one gap exists in said layer exposing said address electrode and said landing electrode; d) at least one hinge formed on said support layer such that said hinge is suspended over said gap; e) at least one deflection element formed upon said at least one hinge, wherein said deflection element is positioned to be suspended over said gap; and f) an oriented monolayer of perfluordecanoic acid (PFDA) formed upon said landing electrode so that when said address electrode is activated and said deflection element twists about said hinge and touches said landing electrode, said landing electrode and said deflection element do not stick together.
