    Abstract: Disclosed herein is a method of improving the adhesion of a hydrophobic self-assembled monolayer (SAM) coating to a surface of a MEMS structure, for the purpose of preventing stiction. The method comprises treating surfaces of the MEMS structure with a plasma generated from a source gas comprising oxygen and, optionally, hydrogen. The treatment oxidizes the surfaces, which are then reacted with hydrogen to form bonded OH groups on the surfaces. The hydrogen source may be present as part of the plasma source gas, so that the bonded OH groups are created during treatment of the surfaces with the plasma. Also disclosed herein is an integrated method for release and passivation of MEMS structures which may be adjusted to be carried out in a either a single chamber processing system or a multi-chamber processing system.

    Abstract: The invention proposes a method for manufacturing micromechanical components, and a micromechanical component, in which a movable element (4) is produced on a sacrificial layer (2). In a subsequent step the sacrificial layer (2) beneath the movable element (4) is removed so that the movable element (4) becomes movable. After removal of the sacrificial layer (2), a protective layer (7) is deposited on a surface of the movable element (4). Silicon oxide and/or silicon nitride is used for the protective layer (7).

    Abstract: There are many inventions described and illustrated herein. In one aspect, the present invention is directed to a MEMS device, and technique of fabricating or manufacturing a MEMS device, having mechanical structures encapsulated in a chamber prior to final packaging and a contact area disposed at least partially outside the chamber. The contact area is electrically isolated from nearby electrically conducting regions by way of dielectric isolation trench that is disposed around the contact area. The material that encapsulates the mechanical structures, when deposited, includes one or more of the following attributes: low tensile stress, good step coverage, maintains its integrity when subjected to subsequent processing, does not significantly and/or adversely impact the performance characteristics of the mechanical structures in the chamber (if coated with the material during deposition), and/or facilitates integration with high-performance integrated circuits. In one embodiment, the material that encapsulates the mechanical structures is, for example, silicon (polycrystalline, amorphous or porous, whether doped or undoped), silicon carbide, silicon-germanium, germanium, or gallium-arsenide.
