    Abstract: A method for fabricating a MEMS device having a fixing part fixed to a substrate, a connecting part, a driving part, a driving electrode, and contact parts, includes patterning the driving electrode on the substrate; forming an insulation layer on the substrate; patterning the insulation layer and etching a fixing region and a contact region of the insulation layer; forming a metal layer over the substrate; planarizing the metal layer until the insulation layer is exposed; forming a sacrificial layer on the substrate; patterning the sacrificial layer to form an opening exposing a portion of the insulation layer and the metal layer in the fixing region; forming a MEMS structure layer on the sacrificial layer to partially fill the opening, thereby forming sidewalls therein; and selectively removing a portion of the sacrificial layer by etching so that a portion of the sacrificial layer remains in the fixing region.

    Abstract: Trilayered Beam MEMS Device and Related Methods. According to one embodiment, a method for fabricating a trilayered beam is provided. The method can include depositing a sacrificial layer on a substrate and depositing a first conductive layer on the sacrificial layer. The method can also include forming a first conductive microstructure by removing a portion of the first conductive layer. Furthermore, the method can include depositing a structural layer on the first conductive microstructure, the sacrificial layer, and the substrate and forming a via through the structural layer to the first conductive microstructure. Still furthermore, the method can include the following: depositing a second conductive layer on the structural layer and in the via; forming a second conductive microstructure by removing a portion of the second conductive layer, wherein the second conductive microstructure electrically communicates with the first conductive microstructure through the via; and removing a sufficient amount of the sacrificial layer so as to separate the first conductive microstructure from the substrate, wherein the structural layer is supported by the substrate at a first end and is freely suspended above the substrate at an opposing second end.

    Abstract: A microstructure comprising a substrate (1), a patterned structure (beam member) (2) suspended over the substrate (1) with an air-space (4) therebetween and supporting structure (3) for suspending the patterned structure (2) over the substrate (1).The microstructure is prepared by using a sacrificial layer (7) which is removed to form the space between the substrate (1) and the patterned structure (2) adhered to the sacrificial layer. In the case of using resin as the material of the sacrificial layer, the sacrificial layer can be removed without causing sticking, and an electrode can be provided on the patterned structure.The microstructure can have application as electrostatic actuator etc., depending on choice of shape and composition.

    Abstract: A process for fabricating a suspended microelectromechanical system (MEMS) structure comprising epitaxial semiconductor functional layers that are partially or completely suspended over a substrate. A sacrificial release layer and a functional device layer are formed on a substrate. The functional device layer is etched to form windows in the functional device layer defining an outline of a suspended MEMS device to be formed from the functional device layer. The sacrificial release layer is then etched with a selective release etchant to remove the sacrificial release layer underneath the functional layer in the area defined by the windows to form the suspended MEMS structure.
