    Abstract: A non-volatile memory device and method of manufacturing a non-volatile micro-electromechanical memory cell. The method comprises the first step of depositing a first layer of sacrificial material on a substrate by use of Atomic Layer Deposition The second step of the method is providing a cantilever (101) over at least a portion of the first layer of sacrificial material. The third step is depositing, by use of Atomic Layer Deposition, a second layer of sacrificial material over the first layer of sacrificial material and over a portion of the cantilever such that a portion of the cantilever is surrounded by sacrificial material. The fourth step is providing a further layer material (107) which covers at least a portion of the second layer of sacrificial material. Finally, the last step is etching away the sacrificial material surrounding the cantilever, thereby defining a cavity (102) in which the cantilever is suspended.

    Abstract: Multilayer structures are electrochemically fabricated from at least one structural material ( e.g . nickel), that is configured to define a desired structure and which may be attached to a substrate, and from at least one sacrificial material ( e.g. copper) that surrounds the desired structure. After structure formation, the sacrificial material is removed by a multi-stage etching Operation. In some embodiments sacrificial material to be removed may be located within passages or the like on a substrate or within an add-on component. The multi-stage etching Operations may be separated by cleaning Operations, or barrier material removal Operations, or the like. Barriers may be fixed in position by contact with structural material or with a substrate or they may be solely fixed in position by sacrificial material and are thus free to be removed after all retaining sacrificial material is etched.

    Abstract: A microelectromechanical system is fabricated from a substrate having a handle layer, a silicon sacrificial layer and a device layer. A micromechanical structure is etched in the device layer and the underlying silicon sacrificial layer is etched away to release the micromechanical structure for movement. One particular micromechanical structure described is a micromirror.

    Abstract: A method of making a micro electro-mechanical gyroscope. A cantilevered beam structure, firstportions of side drive electrodes and a mating structure are defined on a first substrate or wafer;and at least one contact structure, second portions of the side drive electrodes and a matingstructure are defined on a second substrate or wafer, the mating structure on the second substrateor wafer being of a complementary shape to the mating structure on the first substrate or waferand the first and second portions of the side drive electrodes being of a complementary shape to each other. A bonding layer, preferably a eutectic bonding layer, is provided on at least one of the mating structures and one or the first and second portions of the side drive electrodes. The matingstructure of the first substrate is moved into a confronting relationship with the mating structureof the second substrate or wafer. Pressure is applied between the two substrates so as to cause a bond to occur between the two mating structures at the bonding or eutectic layer and alsobetween the first and second portions of the side drive electrodes to cause a bond to occurtherebetween. Then the first substrate or wafer is removed to free the cantilevered beam structurefor movement relative to the second substrate or wafer. The bonds are preferably eutectic bonds.
