Patent ID: 7972886

Claim:
A method of manufacturing a MEMS device comprising the steps of: (a) preparing a substrate that includes a supporting member and a conductor provided with interposing a space between the conductor and the supporting member and that has a first planar area and a second planar area in contact with the first planar area; (b) after the step (a), forming a hole in the conductor in the second planar area, the hole penetrating in a thickness direction of the substrate; (c) after the step (b), providing a fixing material through the hole to be deposited on the supporting member and further filling the hole with the fixing material, thereby fixing the supporting member and the conductor in the second planar area with the fixing material; and (d) after the step (c), patterning the conductor, thereby forming a fixing portion from the conductor in the second planar area and forming a movable portion and a beam from the conductor in the first planar area, the beam connecting the movable portion and the fixing portion, wherein the substrate has a third planar area surrounding the first planar area and the second planar area, in the step (b), a hole penetrating in a thickness direction of the substrate is formed in the conductor in the third planar area, in the step (c), in the third planar area, the fixing material is provided through the hole to be deposited on the supporting member, and further the hole is filled with the fixing material, thereby fixing the supporting member and the conductor in the third planar area with the fixing material, in the step (d), a base is formed from the conductor in the third planar area, and the method further comprises, after the step (d), a step (e) of bonding a cap onto the base, the cap covering the first planar area and the second planar area.
