  • Patent number: 8653838
    Abstract: A soot sensor for the detection of soot particles in an exhaust gas flow, having interdigitally engaged measurement electrodes applied on a substrate. An electrical resistance between the measurement electrodes is a measure of soot load of the exhaust gas flow. The measurement electrodes are divided into two regions, a first region in which no soot particles can be deposited and a second region where soot particles are deposited from the exhaust gas flow. The first region and the second region are exposed simultaneously to the other conditions prevailing in the exhaust gas flow.

  • Publication number: 20130283887
    Abstract: A method for operating a soot sensor in the exhaust gas tract of an internal combustion engine. The soot sensor includes an inter-digital electrode structure to which a measurement voltage is applied. Soot particles from the exhaust gas flow deposit themselves on the inter-digital electrode structure and an measuring current is evaluated as a measurement for the soot concentration of the soot sensor. A heating element for burning clean the inter-digital electrode structure is provided. The method for operating the soot sensor has good measurement results and the shortest possible idle time. To this end, a point in time for burning clean the soot sensor is determined in accordance with the operational state of the internal combustion engine and then, the burning clean of the inter-digital electrode structure starts by heating the soot sensor by the heating element.

  • Publication number: 20130115773
    Abstract: When forming sophisticated high-k metal gate electrode structures on the basis of a replacement gate approach, pronounced loss of the interlayer dielectric material may be avoided by inserting at least one surface modification process, for instance in the form of a nitridation process. In this manner, leakage paths caused by metal residues formed in the interlayer dielectric material may be significantly reduced.

  • Patent number: 8419334
    Abstract: A magnetized nut for fastening a compressor wheel of an exhaust turbocharger to a turbo shaft. The nut has a base body made of a non-magnetic material forming a hollow space for accommodating a magnetic material, and a method for the production of the magnetized nut.

  • Publication number: 20130090866
    Abstract: A diagnostic method for a soot sensor that lies in an exhaust gas system of an internal combustion engine. First, a first temperature in the exhaust gas system is detected, and it is determined whether the detected first temperature is below a 100° C. If this is the case, a first measured value is then detected with the soot sensor and compared with a specifiable threshold value. If the first measured value exceeds the specifiable threshold value, the soot sensor is determined to be operating properly.

  • Patent number: 8338306
    Abstract: In a replacement gate approach, the polysilicon material may be efficiently removed during a wet chemical etch process, while the semiconductor material in the resistive structures may be substantially preserved. For this purpose, a species such as xenon may be incorporated into the semiconductor material of the resistive structure, thereby imparting a significantly increased etch resistivity to the semiconductor material. The xenon may be incorporated at any appropriate manufacturing stage.

    Abstract: A particle sensor arranged in an exhaust duct such that particles from the exhaust-gas flow accumulate on and/or between at least two sensor electrodes when a voltage greater than a limit voltage is applied between the two sensor electrodes and substantially no particles accumulate if the voltage is lower than the limit voltage. During a first time period, a first voltage greater than the limit voltage is applied between the sensor electrodes. During a second time period, a second voltage, lower than the limit voltage, is applied between the sensor electrodes, and/or the particle sensor is heated to a predefined temperature, such that substantially no particles accumulate on and/or between the at least two sensor electrodes. Following the second time period, a third voltage greater than the limit voltage is applied between the sensor electrodes.

  • Publication number: 20120235285
    Abstract: When forming complex metallization systems on the basis of copper, the very last metallization layer may receive contact regions on the basis of copper, the surface of which may be passivated on the basis of a dedicated protection layer, which may thus allow the patterning of the passivation layer stack prior to shipping the device to a remote manufacturing site. Hence, the protected contact surface may be efficiently re-exposed in the remote manufacturing site on the basis of an efficient non-masked wet chemical etch process.

  • Patent number: 8071442
    Abstract: A strain-inducing semiconductor alloy may be formed on the basis of cavities which may have a non-rectangular shape, which may be maintained even during corresponding high temperature treatments by providing an appropriate protection layer, such as a silicon dioxide material. Consequently, a lateral offset of the strain-inducing semiconductor material may be reduced, while nevertheless providing a sufficient thickness of corresponding offset spacers during the cavity etch process, thereby preserving gate electrode integrity. For instance, P-channel transistors may have a silicon/germanium alloy with a hexagonal shape, thereby significantly enhancing the overall strain transfer efficiency.

  • Patent number: 8021942
    Abstract: In the process sequence for replacing conventional gate electrode structures by high-k metal gate structures, the number of additional masking steps may be maintained at a low level, for instance by using highly selective etch steps, thereby maintaining a high degree of compatibility with conventional CMOS techniques. Furthermore, the techniques disclosed herein enable compatibility to front-end process techniques and back-end process techniques, thereby allowing the integration of well-established strain-inducing mechanisms in the transistor level as well as in the contact level.
