    Abstract: An acceleration detection device is provided which is capable of detecting accelerations in two or more directions. The base end of a beam is fixed to a support section on a board. A weight is provided in the front end of the beam which is formed so as to extend horizontally along the board surface with a gap with it and the surface of the board. The position of the center of gravity G of the weight is set at a position spaced perpendicularly apart from the center axis of the beam in order that the inertial moment acts when an acceleration along the length (in the X direction) of the beam is applied. The front end surface of the weight is formed into an upright surface of a movable electrode, and a fixed electrode is formed at a position facing the movable electrode with a gap therebetween. When an acceleration in the X or Y direction is applied, the beam is flexed upwardly or downwardly in proportion to the magnitude of the acceleration, causing the weight to be inclined upwardly or downwardly while being displaced upwardly or downwardly. Thus, the electrostatic capacity between the movable electrode and the fixed electrode increases or decreases. The magnitude of the acceleration can be detected on the basis of the amount of such change of the electrostatic capacity.

    Abstract: What is described in the present specification are accelerometers using tiny proof masses and piezoresistive force detection. Conventional wisdom would indicate that this approach would not yield useful sensors. However, in fact, according to the invention, such devices are suitable in a wide range of applications. The devices may include deformable hinges to allow the fabrication of three dimensional structures. A new system has been developed which etches silicon highly selectively at moderate temperatures and without hydrodynamic forces potentially damaging to small structures and features. The system is based on the use of the gas phase etchant xenon diflouride, which is an unremarkable white solid at standard temperature and pressure.
