    摘要: A micro-electromechanical (MEM) device has a folded tether spring in which each fold of the spring is surrounded by a rigidly fixed inner structure and outer structure. The fixed inner structure increases restoring force of the spring. The rigidly fixed inner and outer structures each have a major surface that include a plurality of notches of fixed width relative to a distance between the major surface and the spring. Additionally in one form extensions from the major surface of the rigidly fixed inner and outer structures are provided at distal ends thereof to make initial contact with the spring. The notches of the MEM device both reduce surface area contact with the spring and wick moisture away from the spring to minimize stiction.

    摘要: A semiconductor component comprises a substrate (101), a two flexible pressure sensor diaphragms (106, 303) supported by the substrate (101), and a fixed electrode (203) between the two diaphragms (106, 303). The two diaphragms (106, 303) and the fixed electrode (203) are electrodes of two differential capacitors. The substrate (101) has a hole (601) extending from one surface (107) of the substrate (101) to an opposite surface (108) of the substrate (101). The hole (601) is located underneath the two diaphragms (106, 303), and the hole (601) at the opposite surfaces (107, 108) of the substrate (101) is preferably larger than the hole (601) at an interior portion of the substrate (101).

    摘要: A microelectronic assembly and a method for forming the same are provided. The method includes forming first and second lateral etch stop walls in a semiconductor substrate having first and second opposing surfaces. An inductor is formed on the first surface of the semiconductor substrate and a hole is formed through the second surface of the substrate to expose the substrate between the first and second lateral etch stop walls. The substrate is isotropically etched between the first and second lateral etch stop walls through the etch hole to create a cavity within the semiconductor substrate. A sealing layer is formed over the etch hole to seal the cavity.

    摘要: A MEMS sensor packaged with an integrated circuit includes switches and control circuitry. In a test mode, the control circuitry causes the switches to turn off and on such that the first and second capacitance of the MEMS sensor can be monitored individually. During a normal mode of operation, the switches are maintained such that the MEMS sensor packaged with the integrated circuit operates to produce a filtered and trimmed output reflecting the sensed phenomena.

    摘要: A method of manufacturing a sensor includes forming a first electrode (120, 1120), forming a sacrificial layer (520) over the first electrode, and forming a layer (130) over the sacrificial layer where a second electrode (131, 831) is located in the layer. The method further includes removing the sacrificial layer after forming the layer to form a cavity (140) between the first and second electrodes and then sealing the cavity between the first and second electrodes. The layer is supported over the first electrode by a post (133, 833) in the cavity, and the second electrode is movable relative to the first electrode and is movable in response to a pressure external to the cavity.
