Abstract:
Systems and methods for a micro-electromechanical system (MEMS) device are provided. In one embodiment, a system comprises a first outer layer and a first device layer comprising a first set of MEMS devices, wherein the first device layer is bonded to the first outer layer. The system also comprises a second outer layer and a second device layer comprising a second set of MEMS devices, wherein the second device layer is bonded to the second outer layer. Further, the system comprises a central layer having a first side and a second side opposite that of the first side, wherein the first side is bonded to the first device layer and the second side is bonded to the second device layer.
Abstract:
A MEMS sensor comprises a substrate and at least one proof mass having a first plurality of combs, wherein the proof mass is coupled to the substrate via one or more suspension beams such that the proof mass and the first plurality of combs are movable. The MEMS sensor also comprises at least one fixed anchor having a second plurality of combs. The first plurality of combs is interleaved with the second plurality of combs. Each of the combs in the first plurality of combs and the second plurality of combs comprises a plurality of conductive layers electrically isolated from each other by one or more non-conductive layers. Each conductive layer is individually coupled to a respective electric potential such that fringing electric fields are screened to reduce motion of the first plurality of combs along a sense axis due to the fringing electric fields.
Abstract:
An electronic device includes: an outline configuration including a first surface, a second surface facing opposite from the first surface, and a mounting surface coupled to the first and second surfaces; a first substrate including a first electrode; a second substrate including a second electrode; a resin disposed between the first and second substrates; and an electric element sealed with the resin and having an outline configuration of a polyhedron, the electric element being disposed such that a broadest surface of the polyhedron faces one of the first substrate and the second substrate. The first surface is one surface of the first substrate, the one surface being opposite from another surface of the first substrate on a side adjacent to the resin. The second surface is one surface of the second substrate, the one surface being opposite from another surface of the second substrate on a side adjacent to the resin. The mounting surface includes: an exposed surface of the resin between the first and second substrates, and side surfaces of the first and second substrates adjacent to the exposed surface. The first electrode is disposed at an end of the first surface adjacent to the mounting surface and electrically coupled to the electric element. The second electrode is disposed at an end of the second surface adjacent to the mounting surface and electrically coupled to the electric element.

Abstract:
An inertia force sensor comprising a mass body (11) displaced when a force is applied to the mass body (11), at least one holding beam (12) holding the mass body (11), and a fixing section (13) fixing one end of the holding beam (12) so as to sensing the inertia force acting on the mass body (11) based on the displacement of the mass body (11), characterized in that the mass body (11) has a hollow structure made by removing the inside of a silicon substrate (1) by one process of etching, and the fixing section (13) is at least a part of the main body of the silicon substrate (1). Since the inertia force sensor is made of single crystal silicon, the mechanical characteristics and reliability are greatly imporoved.
