  • Publication number: 20120013881
    Abstract: A method of determining an overlay error. Measuring an overlay target having process-induced asymmetry. Constructing a model of the target. Modifying the model, e.g., by moving one of the structures to compensate for the asymmetry. Calculating an asymmetry-induced overlay error using the modified model. Determining an overlay error in a production target by subtracting the asymmetry-induced overlay error from a measured overlay error. In one example, the model is modified by varying asymmetry p(n?), p(n?) and the calculating an asymmetry-induced overlay error is repeated for a plurality of scatterometer measurement recipes and the step of determining an overlay error in a production target uses the calculated asymmetry-induced overlay errors to select an optimum scatterometer measurement recipe used to measure the production target.

  • Publication number: 20110255066
    Abstract: An apparatus measures properties, such as overlay error, of a substrate divided into a plurality of fields. The apparatus includes a radiation source configured to direct radiation onto a first target of each field of the substrate. Each first target (T4G) has at least a first grating and a second grating having respective predetermined offsets, the predetermined offset (+d) of the first grating being in a direction opposite the predetermined offset (?d) of the second grating. A detector is configured to detect the radiation reflected from each first target and to obtain an asymmetry value for each first target from the detected radiation.

  • Publication number: 20110141444
    Abstract: A scatterometer configured to measure a property of a substrate, includes a radiation source configured to provide a radiation beam; and a detector configured to detect a spectrum of the radiation beam reflected from a target (30) on the surface of the substrate (W) and to produce a measurement signal representative of the spectrum. The apparatus includes a beam shaper (51, 53) interposed in the radiation path between the radiation source and the detector, the beam shaper being configured to adjust the cross section of the beam dependent on the shape and/or size of the target.

  • Publication number: 20110134419
    Abstract: A method and associated apparatus determine an overlay error on a substrate. A beam is projected onto three or more targets. Each target includes first and second overlapping patterns with predetermined overlay offsets on the substrate. The asymmetry of the radiation reflected from each target on the substrate is measured. The overlay error not resultant from the predetermined overlay offsets is determined. The function that enables calculation of overlay from asymmetry for other points on the wafer is determined by limiting the effect of linearity error when determining the overlay error from the function.

  • Publication number: 20100230216
    Abstract: A brake device is disclosed for rail vehicles. In at least one embodiment, the brake device includes an electromagnetic spring pressure brake, the brake force being applied by an elastic force to the part to be braked and a magnetic arrangement being provided for neutralizing the brake force. The magnetic arrangement counteracts the elastic force and consists of a coil arrangement and an armature place that are mobile in relation to each other, the mobile part being connected to the brake element that impinges the part to be braked. The brake device for a rail vehicle according to at least one embodiment of the invention allows a high brake force and short reaction times and is very compact. For this purpose, the mobile part is connected to an axially displaceable plunger which on one end can be impinged upon with the elastic force and which is connected on the other end to the brake element.

  • Publication number: 20100191432
    Abstract: A method is disclosed for braking electrically driven vehicles, in particular rail vehicles. In at least one embodiment, the behaviour of the brake system is configured directly as a function of the system state, i.e. the operating conditions of the vehicle, such as for example the laden state of the vehicle, temperature of the engines and in particular of the magnets, as well as redundancy requirements, and therefore permit the fully functioning mechanical brake which is present in vehicles nowadays to be eliminated.

  • Patent number: 7685726
    Abstract: In probing by scanning a workpiece (71) to be measured using a coordinate measuring machine a stylus tip is moved before the scanning along a scanning path (73) along an initialization path (83) or/and after the scanning path (73) along a finalization path (85). A length (Lv, Ln) of the initialization path, respectively finalization path, is chosen in dependence of parameters of a concrete measuring task, in particular in dependence of a pre-determined scanning speed, a stiffness of the stylus or a mass of the stylus.

  • Patent number: 7644507
    Abstract: A method for scanning a work piece surface uses a coordinate measurement device. A probe element is brought into contact with the surface and the probe element is moved along the surface. The coordinate measurement device has a plurality of degrees of freedom, which are independent of one another, in the possible movements of the probe element with respect to the work piece. Maximum speeds which describe the maximum of a movement speed component of the probe element based on the respective degree of freedom are defined for the degrees of freedom. An estimated path on which the probe element is intended to move during scanning is predefined. The actual scanning path can differ from the estimated scanning path. A maximum scanning speed at which the estimated scanning path can be traveled with a constant speed of the probe element is determined.
