Publication number: 20050219489Abstract: An exposure apparatus performs exposure for a substrate by filling a space between a projection optical system and the substrate with a liquid and projecting an image of a pattern onto the substrate through the liquid by using the projection optical system. The exposure apparatus includes a substrate stage for holding the substrate, a liquid supply unit for supplying the liquid to a side of an image plane of the projection optical system, and a focus/leveling-detecting system for detecting surface information about a surface of the substrate not through the liquid. The exposure apparatus performs liquid immersion exposure for the substrate while adjusting a positional relationship between the surface of the substrate and the image plane formed through the projection optical system and the liquid, on the basis of the surface information detected by the focus/leveling-detecting system. The liquid immersion exposure can be performed at a satisfactory pattern transfer accuracy.Type: ApplicationFiled: June 1, 2005Publication date: October 6, 2005Applicant: NIKON CORPORATIONInventors: Masahiro Nei, Naoyuki Kobayashi, Hiroshi Chiba, Shigeru Hirukawa

Publication number: 20050088634Abstract: The exposure system of the present invention inhibits baseline shift by carrying out temperature control as required by each composite equipment. This exposure system has a first control system that that sets the temperature of a first liquid, and controls the temperature of an object by circulating the first liquid for which the temperature has been set through at least one object of a projection optics and a substrate stage, and a second control system that sets the temperature of a second liquid independent from the first control system, and controls the temperature of a reticle stage by circulating the second liquid for which the temperature has been set through the reticle stage. The first and second control systems have mutually different setting capacities with respect to the size of the temperature range when setting the temperatures of the liquids.Type: ApplicationFiled: September 13, 2004Publication date: April 28, 2005Applicant: Nikon CorporationInventors: Junichi Kosugi, Tetsuo Taniguchi, Naoyuki Kobayashi, Yoshitomo Nagahashi

Patent number: 5870197Abstract: A local air duct directs a temperature-controlled stream of air across two perpendicular sets of interferometer beams which are used to measure the two dimension (X-Y) position of a precision stage in e.g. an optical lithography stepper or step and scan system, or in any other precision coordinate measuring machine. By thereby providing an additional single air flow which is azimuthally directed across both the X and Y direction interferometer beams, the precision of the interferometric measurement is maximized. In addition, a second flow of air is directed downwards from the local air duct, thus providing sufficient air circulation onto the stage when the stage is directly beneath the local duct, even though in that location the stage is otherwise blocked from receiving the main air flow through the chamber.Type: GrantFiled: October 24, 1996Date of Patent: February 9, 1999Assignee: Nikon CorporationInventors: Michael R. Sogard, John K. Eaton, Kyoichi Suwa, Naoyuki Kobayashi
