Patent number: 7876452Abstract: Process tools and methods are disclosed that involve interferometric and other measurements of movements and positions relative to a process position, such as movements and positions of a stage relative to a lithographic optical system. An exemplary apparatus includes a stage that places a workpiece relative to the tool, and that is movable in at least one direction relative to the tool. At least one first interferometer system is situated relative to the stage to determine stage position in a movement direction relative to the process position. A movement-measuring device determines displacement of the tool from the process position. Using data from the interferometer system and movement-measuring device a processor determines a position of the stage relative to the tool. The processor also corrects the determined position for displacement of the tool.Type: GrantFiled: March 4, 2008Date of Patent: January 25, 2011Assignee: Nikon CorporationInventors: Michael R.

Publication number: 20080204682Abstract: By the combination of adjusting optical properties of an optical system by an irradiation unit irradiating non-exposure light on an optical element, which is movable, and adjusting the optical properties of the optical system with an optical properties adjustment unit by moving the optical element, for example, the change in the optical properties of the optical system caused by the temperature distribution of the optical elements whose center is at a position eccentric from the optical axis is corrected. Further, under a dipole illumination condition, in order to make optical properties of an optical system caused by non-rotational symmetry temperature distribution of optical elements in the vicinity of pupils into optical properties that can be corrected more easily by an optical properties adjustment unit, an irradiation unit irradiates non-exposure light on an optical element, which makes the optical element have a rotational symmetry temperature distribution.Type: ApplicationFiled: June 26, 2006Publication date: August 28, 2008Applicant: Nikon CorporationInventors: Yusaku Uehara, Kiyoshi Uchikawa, Satoshi Ishiyama

Patent number: 6485870Abstract: Methods are disclosed for manufacturing masks (reticles) as used in charged-particle-beam (CPB) microlithography. The methods can include inspecting the masks for defects, and repairing the defects. First, a “parent” mask is prepared from circuit-design data. The resulting pattern elements on the parent mask are inspected and compared with the circuit-design data to determine whether the data have been converted accurately into corresponding pattern elements on the parent mask. This inspection can be performed using an optical microscope. Detected mismatches and defects are corrected as required. The parent mask is used as a microlithography mask in the preparation, by “reduction” optical microlithography, a “progeny” mask. The pattern defined by the progeny mask is imaged and the image is digitized for comparison with a digitized image of the parent mask. The digitized images are compared using a computer.Type: GrantFiled: September 20, 2000Date of Patent: November 26, 2002Assignee: Nikon CorporationInventor: Kiyoshi Uchikawa
