20120092636 | Metrology Apparatus, Lithography Apparatus and Method of Measuring a Property of a Substrate - A metrology apparatus is configured to measure a property of a substrate. The metrology apparatus includes an illumination system configured to condition a radiation beam, an objective lens configured to project radiation onto the substrate, a detector configured to detect radiation reflected from a surface of the substrate, and an image field selecting device in the path of the reflected radiation constructed and arranged to select an area of an image field associated with the substrate. The selected area corresponds with a predetermined portion of the substrate. This arrangement may enable selection of different shapes and sizes of targets on the substrate and may enable in-die measurement of selected parameters. | 04-19-2012 |

20110273691 | RADIATION SOURCE, METHOD OF CONTROLLING A RADIATION SOURCE, LITHOGRAPHIC APPARATUS, AND METHOD FOR MANUFACTURING A DEVICE - An EUV radiation source in the form of a plasma is focused at a virtual source point so as to pass through an exit aperture of a source collector module in an EUV lithographic apparatus. Plasma position is controlled in three directions, X, Y and Z using monitoring signals. By exploiting the photoacoustic effect, the monitoring is accomplished in a non-intrusive manner using acoustic sensors coupled to material of a cone which surrounds the exit aperture. Different angular positions of the radiation beam can be deduced by discriminating signals from the different sensors on the basis of relative arrival time or phase, and/or by comparing the amplitude/intensity of the signals. A sequencer function can be used to introduce a sequence of deliberate offsets in the beam position. This allows acoustic signals to be generated and detected for measurement purposes, when the beam would otherwise not impinge on the material. | 11-10-2011 |

20080309915 | METHOD FOR CORRECTING DISTURBANCES IN A LEVEL SENSOR LIGHT PATH - The invention relates to a level sensor for determining a height of a substrate. The level sensor generates one or more measurement beam and directs the measurement beam to a measurement spot on the substrate and produces a reflected measurement beam. The level sensor also generates one or more reference beams. A detector detects both the reflected measurement beam and the reference beam, respectively, and produces a measurement signal and a reference signal, respectively, the measurement signal being indicative for the height at the measurement spot. A processor that receives these signals and corrects the measurement signal based on the reference signal. The level sensor has an optical arrangement in a predetermined area close to where the substrate is to be located. The measurement beam and the reference beam propagate along substantially equal optical paths of propagation in the predetermined area. The optical arrangement deviates the reference beam from the substantially equal optical paths of propagation in the predetermined area such that the at least one reference beam does not hit the substrate. | 12-18-2008 |

20090049963 | TOOL BIT WITH MULTIPLE CUTTING TIPS - A tool bit suited to use in a machining apparatus for lathing of photoreceptor blanks includes a cutting portion which defines a plurality of projections. During lathing, the projections extend into the blank successively greater distances. When the blank is rotated, each projection cuts a successively radially inward portion of the workpiece. The resulting swarf is thinner and generally easier to handle than for a tool with a single cutting edge, thereby enabling vacuum suction of the swarf. | 02-26-2009 |

20110020850 | METHOD OF DETERMINING ENZYMATIC ACTIVITY IN BIOLOGICAL MEDIA - A reliable, fast and convenient method is provided to determine the change in concentration of enzyme in time in a biological medium in the presence of a signal substrate that corrects for substrate consumption, color-dependency of the signal and non-linearity between the concentration of the leaving group of the signal substrate and the amount of signal. The method comprises the measurement of a calibrator curve in a suitable medium, such as a buffer, to determine the characteristics of the measured curve. These characteristics will then allow to obtain this whole curve or a sufficient part thereof again through a mathematical procedure based on a single-point measurement in a sample of a medium in which the enzyme generation takes place. This has the great advantage that there is no need to measure the whole calibrator curve in each individual medium, since a single-point measurement is adequate. | 01-27-2011 |
