Abstract:
The present invention generally relates to a mechanism for testing a MEMS hysteresis. A power management circuit may be coupled to the electrodes that cause the movable plate that is disposed between the electrodes in a MEMS device to move. The power management circuit may utilize a charge pump, a comparator and a resistor ladder.
Abstract:
Micro-Electro-Mechanical System (MEMS) structures, methods of manufacture and design structures are provided. The method of forming a MEMS structure includes forming fixed actuator electrodes (115) and a contact point on a substrate. The method further includes forming a MEMS beam (100) over the fixed actuator electrodes and the contact point. The method further includes forming an array of actuator electrodes (105') in alignment with portions of the fixed actuator electrodes, which are sized and dimensioned to prevent the MEMS beam from collapsing on the fixed actuator electrodes after repeating cycling. The array of actuator electrodes are formed in direct contact with at least one of an underside of the MEMS beam and a surface of the fixed actuator electrodes.

Abstract:
The invention concerns a microsystem, in particular for producing microswitches or microvalves, constituted on a substrate (50) and used for producing a shift between a first operating state and a second operating state by means of a heat actuated device with bi-metal switch effect. The heat-actuated device comprises a deformable element (51) connected, by opposite ends, to the substrate (50) so as to present naturally a deflection without stress relative to the substrate surface which faces it, said natural deflection determining the first operating state, the second operating state being produced by the heat-actuated device which induces, by the effect of temperature variation, a deformation of the deformable element (51) tending to reduce its deflection and submitting it to a compressive stress by buckling effect in a direction opposite to its natural deflection.
