Abstract: The disclosed invention relates to achieving micromachined piezoelectrically-actuated diaphragms. The piezoelectric diaphragm includes a central, inactive electrode free region and an annular shaped interdigitated electrode adjacent to the outer periphery of the central region. The diaphragm also may have an inactive annular, electrode free region and an active central, interdigitated electrode region. The diaphragms may be used in, such as, miniature pumps. The pumps may include a plurality of chambers to generate peristaltic pumping of fluids.

Abstract: A solid state compact ion gauge includes an inlet, a gas ionizer, and a detector all formed within a cavity in a semiconductor substrate. The gas ionizer can be a solid state electron emitter with ion optics provided by electrodes formed in the cavity through which the cavity is evacuated by differential pumping. Preferably, the substrate is formed in two halves. The substrate halves are then bonded together after the components are provided therein.

Abstract: A method of manufacturing a miniature electromechanical system (MEMS) device includes the steps of forming a moving member on a first substrate such that a first sacrificial layer is disposed between the moving member and the substrate, encapsulating the moving member, including the first sacrificial layer, with a second sacrificial layer, coating the encapsulating second sacrificial layer with a first film formed of a material that establishes an hermetic seal with the substrate, and removing the first and second sacrificial layers.
