  • Patent number: 7889207
    Abstract: An image apparatus (10) for providing an adjusted image (242) of a scene (236) includes a capturing system (16) and a control system (24). The capturing system (16) captures an underexposed first frame (240) that is defined by a plurality of pixels (240A), including a first pixel and a second pixel. The first frame (240) includes at least one of a first texture region (240S) and a second texture region (240T). The control system (24) can analyze information from the pixels (240A) and determine if the first pixel has captured a portion of the first texture region (240S) or the second texture region (240T). Further, the control system (16) can analyze information from the pixels (240A) and to determine if the second pixel has captured a portion of the first texture region (240S) or the second texture region (240T). With this design, the control system (16) can reduce the noise in the first frame (240) to provide a well exposed adjusted image (242).

  • Patent number: 7821615
    Abstract: A liquid jet and recovery system for an immersion lithography apparatus has arrays of nozzles arranged to have their openings located proximal to an exposure region through which an image pattern is projected onto a workpiece such as a wafer. These nozzles are each adapted to serve selectively either as a source nozzle for supplying a fluid into the exposure region or as a recovery nozzle for recovering the fluid from the exposure region. A fluid controlling device functions to cause nozzles on selected one or more sides of the exposure region to serve as source nozzles and to cause nozzles on selected one or more of the remaining sides to serve as recovery nozzles such that a desired flow pattern can be established for the convenience of immersion lithography.

  • Publication number: 20100149513
    Abstract: An immersion lithography system compensates for displacement of the final optical element of the optical assembly caused by the immersion fluid. The system includes an optical assembly to project an image defined by a reticle onto a wafer. The optical assembly includes a final optical element spaced from the wafer by a gap. An immersion element supplies an immersion fluid into the gap and recovers any immersion fluid that escapes the gap. A fluid compensation system applies a force to the final optical element of the optical assembly to compensate for pressure variations of the immersion fluid.

    Abstract: A camera (210) for providing an adjusted image (214) of a scene (12) includes an apparatus frame (224), an optical assembly (222), a capturing system (226), and a control system (232). The optical assembly (222) is adjustable to alternatively be focused on a first focal area (356A) and a second focal area (356B) that is different than the first focal area (356A). The capturing system (226) captures a first captured image (360A) when the optical assembly (222) is focused at the first focal area (356A) and captures a second captured image (360B) when the optical assembly (222) is focused at the second focal area (356B). The control system (232) provides the adjusted image (214) of the scene (12) based upon the first captured image (360A) and the second captured image (360B). Additionally, the control system (232) can perform object depth extraction of one or more objects (16) (18) (20) in the scene (12).

  • Patent number: 7688421
    Abstract: An immersion lithography system that compensating for any displacement of the optical caused by the immersion fluid. The system includes an optical assembly (14) to project an image defined by the reticle (12) onto the wafer (20). The optical assembly includes a final optical element (16) spaced from the wafer by a gap (24). An immersion element (22) is provided to supply an immersion fluid into the gap and to recover any immersion fluid that escapes the gap. A fluid compensation system is provided for the force on the final optical element of the optical assembly caused by pressure variations of the immersion fluid. The resulting force created by the varying pressure may cause final optical element to become displaced. The fluid compensation system is configured to provide a substantially equal, but opposite force on the optical assembly, to prevent the displacement of the final optical element.

  • Publication number: 20100071216
    Abstract: A utility knife blade comprising a blade body defining a first side, a second side opposite the first side, a back edge and a cutting edge opposite the back edge. The cutting edge includes a plurality of serrated portions and substantially non-serrated portions. The blade further defines two opposing lateral edges extending between the back edge and the cutting edge. A plurality of score lines laterally spaced relative to each other along the cutting edge extend across at least one of the first and second sides of the blade between the cutting edge and the back edge, the score lines defining a plurality of blade segments therebetween. The score lines extend between the non-serrated portions of the cutting edge and the back edge so that the serrated portions avoid contact with the score lines to facilitate the breaking off of each cutting segment when desired.

  • Publication number: 20100053588
    Abstract: A new and useful optical imaging process is provided for imaging of a plurality of substrates, in a manner that makes efficient use of an optical imaging system with the capability to image a single reticle to a pair of imaging locations, and addresses the types of substrate stage movement patterns to accomplish such imaging in an efficient and effective manner. At least three substrates are imaged by moving their substrate stages in patterns whereby (i) two of the substrates are completely imaged at respective imaging locations, (ii) a substrate on at least one of the three stages is partially imaged at one imaging location and then partially imaged at the other imaging location, and (iii) the movement of the stages of the three substrates is configured to avoid movement of the stages of the three substrates in paths that would cause interference between movement of any one substrate stage with movement of any of the other substrate stages.

  • Patent number: 7612892
    Abstract: A new and useful imaging concept is provided that is designed to improve the manner in which control information for an imaging optical system such as a lithographic imaging optical system can be generated. An imaging optical system comprises imaging optics defining a primary optical path along which a primary image is imaged, and a measurement optical path is established and includes at least part of the primary optical path. The imaging optical system is configured to obtain information from the measurement optical path for use in providing control information for the imaging optical system. Such a system is particularly useful for measuring the topography of a large region of the surface under investigation, like the entire instantaneous field of a wafer, instead being limited to a small patch or set of patches.

  • Publication number: 20090236543
    Abstract: A method and system is provided that takes advantage of the atmospheric transmission properties of the Hydrogen Lyman-? radiation line (121.6 nm wavelength) to illuminate a sample with high energy VUV photons at least partially in an atmospheric environment. Thus, according to the principles of the present invention, a sample is illuminated by radiation at the Hydrogen Lyman-? radiation line (121.6 nm wavelength), at least partially in an atmospheric environment, and luminescent radiation from the sample at longer wavelengths is detected. The high energy illuminating photons generate luminescent radiation from the sample at longer wavelengths, typically in the visible wavelength range, and this radiation can then be imaged, e.g. with a normal visible microscope.
