  • Patent number: 7884877
    Abstract: In an imaging device according to one aspect of the invention, an amplitude demand Ac is specified according to a wobbling amplitude Ai required for detection of a hill-climbing direction based on an F value and a wobbling amplitude Ag required for detection of the hill-climbing direction based on an AGC gain. An allowable amplitude Am set for preventing a potential image shake caused by a magnification change with a position shift of a compensator lens in wobbling is specified corresponding to a zoom position and an object distance. When Ac>Am, the control procedure restricts the wobbling amplitude to Am and increases a sampling number of AF evaluation values to be detected at respective positions in wobbling, in order to ensure the sufficient detection performance of the hill-climbing direction. When Ac?Am on the other hand, the control procedure sets Ac to the wobbling amplitude.

  • Patent number: 7884918
    Abstract: An exposure apparatus includes a first measurement device, a second measurement device, and a controller. The first measurement device measures the position of a substrate stage in the optical axis direction when the substrate stage is scanned in the first direction. The second measurement device measures the surface positions of the substrate in the optical axis direction at a plurality of measurement points on one straight line extending in the second direction on the substrate. The controller controls the second measurement device to measure at least one identical region on the substrate at different measurement points of the plurality of measurement points both before and after the substrate stage moves in steps in the second direction, and calculates a measurement error of the first measurement device attributed to the driving of the substrate stage in the second direction based on the measurement result obtained by the second measurement device.

  • Patent number: 7884919
    Abstract: A device manufacturing method includes transferring a pattern from a patterning device onto a substrate. The method includes bringing the patterning device and the support together, and applying a substantially stationary force between the patterning device and the support to hold the patterning device. The patterning device is now excited by a substantially dynamic force to enable a micro slipping thereof. Then, the patterning device is aligned, and the pattern is transferred from the patterning device onto the substrate. The patterning device may be excited with an alternating acceleration. When the patterning device is excited, the patterning device is allowed to settle with respect to the support, thereby improving a friction therebetween to reduce a risk of slipping or local slipping of the patterning device.
