Abstract: A device for reinforcing, sealing or damping a structural element in a motor vehicle includes: a support with a fastening element for prefixing the device in the structural element; and an expandable adhesive arranged on the support for connecting the support to the structural element; wherein the fastening element is arranged on an elevation of the support, wherein the elevation is raised from a surrounding surface of the support, and wherein the expandable adhesive is arranged at least partially around the elevation on the surrounding surface of the support.

Abstract: An electrostatic chuck includes an embedded electrode receiving a first voltage to electrostatically attract a semiconductor substrate to the electrostatic chuck. A plurality of current loops are disposed in at least one of the electrostatic chuck and an edge ring surrounding the electrostatic chuck. The current loops are laterally spaced apart. Each current loop is a wire formed into a loop. One or more DC power sources are electrically connected to the current loops. A controller supplies the first voltage to the embedded electrode, supplies a DC current to the current loops from the power sources, and controls the power sources. Each current loop is independently operable and generates a localized DC magnetic field proximate to the semiconductor substrate on receiving the DC current during plasma processing of the semiconductor substrate to adjust the plasma processing of the semiconductor substrate. The localized DC magnetic field does not generate plasma.

Abstract: A component of a substrate support assembly such as a substrate support or edge ring includes a plurality of current loops incorporated in the substrate support and/or the edge ring. The current loops are laterally spaced apart and extend less than halfway around the substrate support or edge ring with each of the current loops being operable to induce a localized DC magnetic field of field strength less than 20 Gauss above a substrate supported on the substrate support during plasma processing of the substrate. When supplied with DC power, the current loops generate localized DC magnetic fields over the semiconductor substrate so as to locally affect the plasma and compensate for non-uniformity in plasma processing across the substrate.

Abstract: An arrangement for processing a semiconductor substrate in a plasma processing system is disclosed. The arrangement includes providing a RF coupling structure having a first terminal and a second terminal, the first terminal being coupled with a first electrical measuring device, the second terminal being coupled with a second electrical measuring device. The arrangement also includes coupling a compensating circuit to the second terminal. The arrangement further includes providing a feedback circuit coupled to receive information from the first electrical measuring device and the second electrical measuring device, an output of the feedback circuit being employed to control the compensating circuit in order to keep a ratio between a first electrical value at the first terminal and a second electrical value at the second terminal substantially at a predefined value.

Abstract: A method involving plasma cleaning of deposit residues in process chamber using duo-step wafer-less auto clean method is detailed. Specifically, the method involves cleaning the processing chamber by flowing a first gaseous composition with at least about 75% of fluorine-containing compound of the formula XyFz, into a processing chamber and then forming a first etchant plasma which removes silicon and silicon based byproducts from the interior surfaces of the processing chamber. The method then involves flowing a second gaseous composition into the processing chamber with a composition of at least about 50% O2 and forming a plasma from the second gaseous composition to provide a second etchant plasma which removes carbon and carbon based byproducts from the interior surfaces of the processing chamber. A system configured to execute the two step cleaning process is also provided.

Abstract: A gas in a vacuum plasma processing chamber is ignited to a plasma by subjecting the gas to an r.f. field derived from an r.f. source having a frequency and power level sufficient to ignite the gas into the plasma and to maintain the plasma. The r.f. field is supplied to the gas by a reactive impedance element connected via a matching network to the r.f. source. The matching network includes first and second variable reactances that control loading of the source and tuning a load, including the reactive impedance element and the plasma, to the source. The value of only one of the reactances is varied until a local maximum of a function of power coupled between the source and the load is reached. The value of only the other reactance is varied until a local maximum of the function is reached. The two varying steps are then repeated as necessary.

Abstract: An r.f. field is supplied by a reactive impedance element to a plasma in a vacuum plasma processing chamber. The element and source are connected via a matching network including first and second variable reactances that control loading of the source and tuning a load, including the reactive impedance element and the plasma, to the source. The values of the first and second variable reactances are changed to determine the amount the first variable reactance is to change for each unit change of the second variable reactance to attain the best match between the impedances seen looking into and out of output terminals of the r.f. source. Then the values of the first and second variable reactances are varied simultaneously based on the determination until the best impedance match between the impedances seen looking into and out of output terminals of the r.f. source is attained.
