The detection structure for a MEMS accelerometer is formed by a substrate; a first movable mass and a second movable mass which extend at a distance from each other, suspended on the substrate and which are configured to undergo a movement, with respect to the substrate, in response to an acceleration. The detection structure also has a first movable electrode integral with the first movable mass; a second movable electrode integral with the second movable mass; a first fixed electrode integral with the substrate and configured to form, with the first movable electrode, a first variable capacitor; and a second fixed electrode integral with the substrate and configured to form, with the second movable electrode, a second variable capacitor. The detection structure has an insulation region, of electrically insulating material, which is suspended on the substrate and extends between the first movable mass and the second movable mass.

A MEMS device and method of forming the same includes paired masses suspended above a substrate includes linkages that couple pairs of masses to each other. Inner sense linkages couple interior edges of adjacent masses to each other. The inner sense linkages are configured to exhibit a first stiffness when the adjacent masses coupled to each inner sense linkage move out-of-phase relative to each other along a preferred axis of the inner sense linkages and to exhibit a second, increased stiffness in response to in-phase motion of the adjacent masses coupled to each inner sense linkage.

The present invention introduces the ASIC integrated MEMS device with exposed bond-pads from bottom attached ASIC and method for making the same. The ASIC integrated MEMS device with exposed bond-pads from bottom attached ASIC can be especially used for micromirror array MEMS devices. With the present invention and technology, individually controlling of thousands of micromirrors becomes possible and bring easier fabrication method. With the present invention and technology, individually controllable micromirror array can implement easier control method and more compact packing becomes feasible. With help of the present invention scheme, more complicated light modulating device scheme can be implemented with micromirror array or MEMS device with a large number of controlling channels. Scheme, apparatus, and method are disclosed in the present invention.
