  • Patent number: 7817244
    Abstract: 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.

  • Patent number: 7619854
    Abstract: A first component defines a threaded bore. A second component is kept in contact with the first component. A clamping screw penetrates through the second component and is screwed in the threaded bore. A lubricating agent film is interposed between the threaded bore and the clamping screw. The lubricating agent film is made of a macromolecular compound having a polar end group. The lubricating agent film serves to reduce the friction between the threaded bore and the clamping screw. Generation of dust is prevented when the clamping screw is being screwed into the threaded bore. In addition, the clamping screw exhibits a larger axial force at a certain amount of a fastening torque as compared with a conventional clamping screw. A larger axial force can thus be applied to hold the second component onto the first component.

  • Patent number: 7602945
    Abstract: Disclosed is an apparatus which, even when it becomes impossible to take an image of a mobile object due to existence of an obstacle to hide the mobile object, is capable of making a simulatory screen display of the mobile object, thereby notifying a driver of a risk of collision with the mobile object. Even when it is impossible to take an image of the mobile object because of existence of an obstacle, the apparatus displays a simulated picture image of the mobile object superimposed on an actual picture image, by obtaining an optical flow or by performing pattern matching. Thus, an effect is obtained that the mobile object is viewed as if transmitted through the obstacle. By notifying the driver of the risk of collision in advance by means of sound or video image perceptible by a human being, the danger of the collision is avoided.
