摘要： A method for checking an exhaust gas cleaning plant connected to an internal combustion engine in an exhaust gas tract that includes a catalytic converter having oxygen storage characteristics as well as a NOx sensor positioned downstream in the exhaust gas tract that emits a sensor signal depending on the NOx and the NH3 concentration in the exhaust gas in which case the internal-combustion engine is operated with a periodic air/fuel ratio oscillating around the value lambda=1 and that the average of the sensor signal is formed over one period or several periods and if the threshold value of the average is exceeded, damage to the monolith of the catalytic converter is detected.

摘要： During the starting of an internal combustion engine with fuel injection, so-called preliminary injections (I) are dispensed according to a certain preliminary injection strategy in order to build up a wall film in the cylinders and simultaneously provide an ignitable mixture for the initial combustion. To avoid a situation where the preliminary charges during the starting phase are too rich or too lean, different quantities of fuel are chosen for the preliminary injections (I), depending on the charges to be expected in the relevant cylinders.

摘要： For a three-way catalytic converter system with a preliminary catalytic converter, a main catalytic converter and an oxygen sensor with a constant characteristic curve disposed between the two catalytic converters, a method for resetting the oxygen concentration in the preliminary catalytic converter and the main catalytic converter in the event of a transition from lean-burn operation to stoichiometric operation includes exposing both catalytic converters to a rich mix until the desired oxygen concentrations have been reached. In the process, the constant measurement signal from the oxygen sensor and the measurement signal from an air mass flow meter are used to calculate the quantity of oxygen that is released to the exhaust gas from the main catalytic converter, in order to end rich-burn operation when a predetermined desired value is reached.

摘要： The present invention provides an improved method and apparatus to measure p-n junction device temperature by testing a device with M-Levels of applied collector current, sensing changes in output characteristics, and calculating the device current offset error and leakage current error due to parasitic parallel resistance where the leakage current error due to parasitic parallel resistance may be treated and eliminated as current offset error. Application of M levels of excitation values, where M is greater than or equal to four, eliminates device series parasitic effects, comprised of voltage offset and a series parasitic resistance, and parallel parasitic effects, comprised of current offset error and leakage current error due to parasitic parallel resistance, from temperature measurements. Since the operating characteristics of the device are temperature dependent, excitation levels applied and output values observed are used to determine junction temperature of the device free of series and parallel parasitic effects.

摘要： A process for cleaning exhaust gas flow from an internal combustion engine using a catalyst, a lambda probe is disposed in the exhaust gas flow upstream from the catalyst and is connected to a controller that actuates the lambda probe, the controller receives a raw signal output from the lambda probe and forms a measurement signal that is supplied to control the internal combustion engine. The process includes regulating operation of the internal combustion engine such that a predetermined value of the lambda probe corresponds to a certain level of the measurement signal. Trimming the certain level of the measurement signal by a set value determined with an additional measuring pickup located downstream of the catalyst is performed, the trimming corrects the certain level of the measurement signal that corresponds to the predetermined value of the lambda probe. Switching the controller to a test mode in predetermined states of operation by the internal combustion engine and determining an actual value of a measurement signal falsification developed in the controller is performed. Compensating the measurement signal inversely to the actual value of the measurement signal falsification takes place. Varying the set value inversely to the actual value of the measurement signal falsification is performed.

摘要： A method for processing a substrate comprising the formation of a metal nitride/metal stack suitable for use as a barrier/liner for sub-0.18 &mgr;m device fabrication. After a metal nitride layer is deposited upon a metal layer, the metal nitride layer is exposed to a treatment step in a nitrogen-containing environment, e.g., a plasma. The plasma treatment modifies the entire metal nitride layer and a top portion of the underlying metal layer. The plasma adds nitrogen to the top portion of the metal layer, resulting in the formation of a nitrated-metal layer. Aside from reducing the microstructure mismatch across the nitride-metal interface, the plasma treatment also densifies and reduces impurities from the deposited nitride layer. The resulting nitride/metal stack exhibits improved film properties, including enhanced adhesion and barrier characteristics. A composite nitride layer of a desired thickness can also be formed by repeating the deposition and treatment cycles of thinner component nitride layers.

摘要： The present invention relates generally to an improved process for providing uniform step coverage on a substrate and planarization of metal layers to form continuous, void-free contacts or vias in sub-half micron applications. In one aspect of the invention, a refractory layer is deposited onto a substrate having high aspect ratio contacts or vias formed thereon. A CVD metal layer is then deposited onto the refractory layer at low temperatures to provide a conformal wetting layer for a PVD metal. Next, a PVD metal is deposited onto the previously formed CVD metal layer at a temperature below that of the melting point temperature of the metal. The resulting CVD/PVD metal layer is substantially void-free. The metallization process is preferably carried out in an integrated processing system that includes both a PVD and CVD processing chamber so that once the substrate is introduced into a vacuum environment, the metallization of the vias and contacts occurs without the formation of an oxide layer over the CVD Al layer.
