摘要:
A device and method for treating the surface of a semiconductor wafer provides a treatment fluid in the form of a dispersion of gas bubbles in a treatment liquid generated at acoustic pressures less than those required to induce cavitation in the treatment liquid. A resonator supplies ultrasonic or megasonic energy to the treatment fluid and is configured to create an interference pattern in the treatment fluid comprising regions of pressure amplitude minima and maxima at an interface of the treatment fluid and the semiconductor wafer.

A method for obtaining diamond particles from aggregate structures which contain diamond particles with an average particle diameter of less than 10 nm. The aggregate structures are heated under a gas atmosphere such that the diamond particles are obtained from the aggregate structures. It is essential that the aggregate structures are heated under a gas atmosphere which, in terms of reactive gases, contains hydrogen gas in a proportion of at least 80%.

The present invention relates to methods for screening molecules and methods to detect protein-protein interactions and means used therein. More specifically, the present invention relates to methods for screening candidate drugs for treating or detecting MIF (macrophage migration inhibitor factor) related diseases. In certain aspects, the present invention involves detecting MIF/Jab1 (c-Jun activation domain binding protein) interactions as a basis for modulating cellular regulatory pathways and for identifying candidate drugs for MIF-related diseases. The invention also provides methods for the identification of molecules which dissociate or prevent interaction or binding between MIF and Jab1.

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.
摘要:
A method and an arrangement for magnetically determining a position using a permanent magnet is described, wherein the vector and local gradient of the magnetic flux density of the permanent magnet is measured using a position sensor, and the position and orientation of the magnetic dipole of the the permanent magnet relative to the position sensor is calculated from the measured values. A spherical permanent magnet having homogenous magnetization is used in the method and the arrangement, preventing previously present cross-sensitivity between the position and orientation determination, and allowing measurement without prior calibration.

The invention is a device and a method for eliminating vibrations of a mechanical structure with at least one electromechanical converter material that is actively connected to the mechanical structure and connected to an electrical circuit with at least one electrical impedance. The electrical circuit is connected to an interface, via which the at least one electrical impedance can be variably adjusted by wireless or wired communications with a control unit that is separated from the electrical circuit in which the electrical impedance features at least one variable ohmic resistor, inductive resistor or capacitor.
