Patent number: 7256865Abstract: Embodiments of the invention provide methods and apparatuses for efficient and cost-effective imaging of alignment marks. For one embodiment, alignment mark imaging is accomplished separately from, and independent of product imaging through use of a relatively low cost, low resolution, imaging tool. For one embodiment a wafer is exposed to low-resolution light source through a reticle having a number of alignment patterns corresponding to desired alignment marks. For one embodiment, global alignment marks are imaged on a backside of a wafer. Various embodiments of the invention obviate the need for a highly accurate stage and a high-resolution imaging device, and therefore reduce processing costs and processing time.Type: GrantFiled: October 24, 2003Date of Patent: August 14, 2007Assignee: ASML Holding N.V.Inventors: Joseph Consolini, Keith Best, Cheng Gui, Alexander Friz

Patent number: 6621557Abstract: Light from a pattern of a mask 3 travels through a first imaging optical system K1 to form a primary image I of the mask pattern. Light from the primary image I travels through a center aperture of a main mirror M1 and a lens component L2 to be reflected by a sub-mirror M2, and the light reflected by the sub-mirror M2 travels through the lens component L2 to be reflected by the main mirror M1. The light reflected by the main mirror M1 travels through the lens component L2 and a center aperture of the sub-mirror M2 to form a secondary image of the mask pattern at a reduction ratio on a surface of wafer 9.Type: GrantFiled: January 10, 2001Date of Patent: September 16, 2003Assignee: Nikon CorporationInventor: Tetsuo Takahashi

Patent number: 6332059Abstract: A lens-fitted photo film unit incorporates a mechanism for taking an exposure, and is pre-loaded with unexposed photo film. A telephoto selectable type indicia is imprinted previously on a first edge of the photo film outside imaging frames in an optical manner. An indicia recorder imprints a magnification indicia on a second edge of the photo film outside the imaging frames in an optical manner each time that one exposure is taken. A combination of the telephoto selectable type indicia and the magnification indicia designates a printing condition for each of the imaging frames.Type: GrantFiled: September 20, 2000Date of Patent: December 18, 2001Assignee: Fuji Photo Film Co., Ltd.Inventors: Kazuo Kamata, Mitsuro Kamata

Patent number: 6084654Abstract: A rolling loop motion picture projector is convertible for projecting images either from a 2-D film strip or from a 3-D film strip. The film is advanced through the same incremental amount irrespective of whether a 2-D film of a 3-D film is being projected. The projector has a single central aperture for projecting 2-D images and respective 3-D images on opposite sides of the central aperture. The images on the 3-D film strip are anamorphically compressed in the direction of film travel by a factor of two and the 3-D apertures are correspondingly sized. Projection lenses associated with the 3-D apertures decompress the images so that images of comparable size appear on the screen irrespective of whether a 2-D film or a 3-D film is being shown.Type: GrantFiled: June 30, 1998Date of Patent: July 4, 2000Assignee: Imax CorporationInventors: Marian Toporkiewicz, Michael A. Gibbon

Patent number: 6048113Abstract: Photographic sheet material is processed using a processing cell through which the sheet material passes. Process liquid is fed from a collapsible storage container to the cell and returned from the cell to the container. The returning liquid is caused to enter the container as a jet stream. A cap assembly for the container comprises a body releasably connected to an upwardly facing mouth of the container. Inlet and outlet passages pass through the body and the inlet passage opening into the container is provided with a cross-sectional area smaller than that of the outlet passage to enable the jet stream to be achieved. Mixing of the returning process liquid in the container in a simple and economical manner is possible without compromising the ability of the container to collapse.Type: GrantFiled: September 4, 1998Date of Patent: April 11, 2000Assignee: Agfa-GevaertInventors: Patrick Van den Bergen, Ronny Van Bouwel

Patent number: 4673251Abstract: A processor for use in processing sheets of photosensitive material has a plurality of processing stations. A plurality of drive rollers define a sheet processing path through the processing stations and are driven to transport a sheet of photosensitive material along that path. The drive rollers at the processing station at the end of the path are driven at a faster rate of rotation than the drive rollers at previous processing stations along the path. The drive rollers of those previous processing stations, however, are mounted to permit said rollers to overrun their driven slower rate of rotation and permit those rollers to rotate at the faster rate of rotation.Type: GrantFiled: December 18, 1985Date of Patent: June 16, 1987Assignee: Pako CorporationInventor: Benjamin H. Sannel
