20080285003 | Linear motor driven automatic reticle blind - A reticle blind which is capable of being opened and closed at a relatively high speed and which does not cause mechanical disturbances or reaction forces. The reticle blind includes two reticle blind assemblies designed to cooperate with one another to control the passing of a laser beam of an exposure system onto a work piece, such as a semiconductor wafer or flat panel display. Each reticle blind assembly includes a linear motor having a mover and a blind configured to be positioned between a first position and a second position by the mover. Each reticle blind assembly also includes a counter mass assembly including a portion of a guide mechanism having at least one guide bar and a stator of the linear motor. The stator of the linear motor and the guide bar are integrated to form the counter mass which is configured to absorb reaction forces that are created when the blind is moved. In various embodiments, the blinds can be configured to operate in the vertical or horizontal orientation. | 11-20-2008 |
20090015806 | Environmental control apparatus, stage apparatus, exposure apparatus and device manufacturing method - An environment control apparatus comprises a first member, which has a first opening, which forms a first space and is formed at least a part and a first surface provided in the vicinity of the first opening, and a movable member, which has a second surface, which is arranged so as to cover the first opening and opposes the first surface, and is capable of relative movement with respect to the first opening while being guided by the first surface, and a gas seal mechanism is formed between the first surface and the second surface, and it is capable of setting the first space to a prescribed status. | 01-15-2009 |
20090190117 | Exposure apparatus, manufacturing method and supporting method thereof - An exposure apparatus includes an illumination optical system that guides illumination light to a mask; a projection optical system that projects the pattern irradiated with the illumination light, onto a substrate; and a supporting device that integrally suspendingly supports at least part of the illumination optical system and the projection optical system, with a supporting member having a flexible structure. | 07-30-2009 |

20090009742 | OPTICAL ELEMENT DRIVING APPARATUS, BARREL, EXPOSURE APPARATUS AND DEVICE MANUFACTURING METHOD - A permanent magnet fixed to a peripheral portion of a lens cell includes two magnets that are joined together so that the north poles face each other and the south poles are exposed. A first driving coil is arranged to face toward exits for lines of magnetic force from the joining surfaces of the north poles of the permanent magnet, and a second driving coil is arranged to face toward entrances for lines of magnetic force in the permanent magnet. The orientation of the lens is adjusted by adjusting the currents supplied to the first driving coil and second driving coil to drive the lens cell in an optical axis direction and horizontal direction in a state in which the lens cell is levitated relative to the cover. | 01-08-2009 |
20090147228 | Exposure apparatus, manufacturing method thereof, and maintenance method of exposure apparatus - A projection optical system PL is used to project an image of a pattern. A manufacturing method of an exposure apparatus includes: a positioning step of positioning the projection optical system at a predetermined position; and a support step of supporting the positioned projection optical system. The positioning step includes a step of moving the projection optical system upward from below at the time of positioning. | 06-11-2009 |
