    Abstract: The invention presents a method for producing microstructured apparatuses for microelectromechanical systems (MEMS). In order to increase the maximum aspect ratio conditioned by physical or chemical microstructuring methods, it is proposed to design flat elements of the apparatus, which are structured such that they are movable relative to one another, to be laterally changeable from a first reference position relative to one another (structuring position) to a second reference position (operating position) in a permanent or irreversible manner. As a result, higher trench capacitances can be formed between structured wall sections. The reference position can be changed by means of integrated drives or by supplying energy from the outside and said change is effected in a direction which is substantially different from the measuring direction. In addition to mechanical work and energy from electrical or magnetic fields, heat can be used to shift location in drives as a result of the action of force on an element or induced changes in length. This method makes it possible to produce highly sensitive sensors for very small excitation signals or to produce economical actuators with an extremely high level of efficiency in the form of low-attenuation, area-optimized, highly capacitive converters, as well as variable vertical capacitors with a high capacitance.

    Abstract: This invention is a novel methodology for precision metrology, sensing, and actuation at the micro- and nano-scale. It is well-suited for tiny technology because it leverages off the electromechanical benefits of the scale. The invention makes use of electrical measurands of micro- or nano-scale devices to measure and characterize themselves, other devices, and whatever the devices subsequently interact with. By electronically measuring the change in capacitance, change in voltage, and/or resonant frequency of just a few simple test structures, a multitude of geometric, dynamic, and material properties may be extracted with a much higher precision than conventional methods.

    Abstract: The present invention relates to a method for producing a micro-mirror actuator and the corresponding actuator. In the method, the actuator is generated from a layered construction made of at least three main layers (101, 103, 107), which are at least sectionally electrically insulated from one another via intermediate layers (102, 104, 106). The layers are structured to form the micro-mirror element and the electrodes, the structuring being performed in such a way that a closed frame (310) is formed from at least the uppermost layer (107) around the inner area of the actuator, which allows a hermetic encapsulation of the inner area by application of a cover plate onto the frame. Furthermore, a conductor level (105), which is electrically insulated from these layers via the intermediate layers, is generated between at least two of the layers and structured to form conductor paths, via which one or more electrodes may be electrically contacted from outside the frame (310) after the formation of contact openings in one or more of the intermediate layers (102, 104, 106).A hermetically sealed encapsulation of the inner area of actuator may already be achieved easily at the wafer level using the method.

    Abstract: A buckling actuator has a connecting section of a supporting beam that is provided with a rotatable supporter for allowing a movable member to be stably maintained at one of two switch positions. A substrate, stationary members, rotatable supporters, and supporting beams support a movable member in a shiftable manner in a y-axis direction, such that the movable member can be shifted between first and second switch positions. Moreover, the rotatable supporters are each provided with arm portions which extend in a radial fashion and support the corresponding supporting beam in a rotatable manner. When the movable member is being shifted, each supporting beam can be rotated without having to bend a corresponding end by a significant amount. Thus, a large barrier ΔE of potential energy of the movable member is set between the first and second switch positions. The movable member can therefore be stably maintained at each of the switch positions even when electric power is not supplied to electrodes. Furthermore, each arm portion prevents the movable member from being displaced in an x-axis direction.
