    Abstract: The present invention generally relates to a method for forming a MEMS device and a MEMS device formed by the method. When forming the MEMS device, sacrificial material is deposited around the switching element within the cavity body. The sacrificial material is eventually removed to free the switching element in the cavity. The switching element has a thin dielectric layer thereover to prevent etchant interaction with the conductive material of the switching element. During fabrication, the dielectric layer is deposited over the sacrificial material. To ensure good adhesion between the dielectric layer and the sacrificial material, a silicon rich silicon oxide layer is deposited onto the sacrificial material before depositing the dielectric layer thereon.

    Abstract: A method for manufacturing a film support beam includes: providing a substrate having opposed first and second surfaces; coating a sacrificial layer on the first surface of the substrate, and patterning the sacrificial layer; depositing a dielectric film on the sacrificial layer to form a dielectric film layer, and depositing a metal film on the dielectric film layer to form a metal film layer; patterning the metal film layer, and dividing a patterned area of the metal film layer into a metal film pattern of a support beam portion and a metal film pattern of a non-support beam portion, wherein a width of the metal film pattern of the support beam portion is greater than a width of a final support beam pattern, and a width of the metal film pattern of the non-support beam portion is equal to a width of a width of a final non-support beam pattern at the moment; photoetching and etching on the metal film layer and the dielectric film layer to obtain the final support beam pattern, the final non-support beam pattern and a final dielectric film layer, wherein the final dielectric film layer serves as a support film of the final support beam pattern and the final non-support beam pattern; and removing the sacrificial layer.

    Abstract: The method of manufacturing an inertial sensor includes: (A) disposing a first mold 120 and a second mold 125 on both surfaces of a predetermined region R in a plate-shaped membrane 110, (B) forming a mass body 130, a post 140, and an upper cap 150 through a plating process or a filling process, (C) disposing a third mold 160 on an exposed surface of the first mold 120 and the mass body 130, and (D) forming a lower cap 170 through the plating process or the filling process. Since the mass body 130 is made of metal by a plating process or a filling process, the density of the mass body 130 may be increased and the mass body 130 may be formed to have a structure of a high aspect ratio, thereby improving the sensitivity of the inertial sensor 100.
