| 20090161088 | Beam Characterization Monitor for Sensing Pointing or Angle of an Optical Beam - The divergence of an optical beam is determined. An optic is configured to provide internal reflection of at least a part of a beam of radiation scanned over varying angles of incidence on the optic. The optic has a film configured to provide a surface plasmon resonance (SPR) effect. A detector is arranged relative to the optic and configured to electronically detect radiation reflected from the optic. The divergence angle of the beam of radiation is calculated based on a change in reflectance relative to angle of incidence. | 2009-06-25 |
| 20090161089 | IMMERSION LITHOGRAPHIC APPARATUS AND DEVICE MANUFACTURING METHOD - A lithographic apparatus includes a liquid supply system configured to supply an immersion liquid between a downstream optical element of a projection system of the lithographic apparatus and the substrate, and a control system which is arranged to drive the substrate table so as to perform an acceleration profile to accelerate the substrate table from a first velocity in a first direction to a second velocity in a second direction. The acceleration profile is asymmetric in time and is dimensioned so that when the substrate table is accelerated according to the acceleration profile, a force to break a meniscus of the immersion liquid remains lower than a force to maintain the meniscus of the immersion liquid. | 2009-06-25 |
