Abstract:
A light source apparatus is equipped with a discharge lamp, which has a glass tube that forms a light emitting part and a base member that is coupled thereto, and a mounting apparatus that holds the discharge lamp via the base member. Therein, the base member has a flange part that contacts positioning plate of the mounting apparatus, and a fixed part that is urged with a pressing force that presses the flange part to the positioning plate. Furthermore, the mounting apparatus has a fixing arm that urges the fixed part by a compression coil spring.
Abstract:
While one ends of ropes are respectively tied to a −Y side leg section and a +Y side leg section of a frame caster, the other ends of the ropes hang down in a −Z direction via a plurality of pulleys fixed to the upper sections of frames that are each separated from an apparatus main body, and a weight having a weight corresponding to a half the weight to be reduced is tied to each of the other ends. In this case, even if the apparatus main body oscillates in vertical or lateral directions (normal directions of the pulleys) owing to the action of a vibration isolation table, the position of the weight only vertically moves by rotation of the pulleys, and the reduced amount of the apparatus weight does not vary. Further, since any coil springs are not used, sympathetic vibration with the apparatus main body and the vibration isolation table does not occur, which allows the attenuation characteristics of the vibration isolation table to be improved. Therefore, the exposure apparatus can be increased in size without inducing the cost rise.

Abstract:
A plurality of air levitation units that jet air to the lower surface of a substrate are placed below the substrate, and the substrate is supported in a noncontact manner so as to be substantially horizontal. Further, a portion subject to exposure of the substrate is held from below in a noncontact manner by a chuck main body that a fixed-point stage has, and a surface position of the portion subject to exposure is adjusted in a pinpoint manner. Consequently, exposure can be performed on the substrate with high precision. Since the chuck main body moves in a scanning direction according to the position of the substrate, the chuck main body can surely hold the substrate even when the substrate proceeds into an exposure area.
Abstract:
A substrate is held by adsorption by a substrate holding frame that is formed into a frame shape and is lightweight, and the substrate holding frame is driven along a horizontal plane by a drive unit that includes a linear motor. Below the substrate holding frame, a plurality of air levitation units are placed that support by levitation the substrate in a noncontact manner such that the substrate is substantially horizontal, by jetting air to the lower surface of the substrate. Since the plurality of air levitation units cover a movement range of the substrate holding frame, the drive unit can guide the substrate holding frame (substrate) along the horizontal plane at high speed and with high precision.

Abstract:
In a liquid crystal exposure apparatus, base pads are respectively placed on two surface plates, and one step board is supported by the base pads. A device main body of an empty-weight cancelling device moves from above one of the surface plates to above the other by moving on the step board, and therefore, a boundary section between the two adjacent surface plates that are separately placed does not function as a guide surface used when the empty-weight cancelling device moves. Accordingly, a fine movement stage that holds a substrate can be guided along an XY plane with high accuracy although the two surface plates are placed apart.
Abstract:
A device production system includes a substrate transport section which transports a substrate; a plurality of exposure sections each of which is capable of exposing the substrate; and a controller which cooperatively controls the substrate transport section and the plurality of exposure sections so that operation states of the plurality of exposure sections are in desired states. Accordingly, it is possible to improve the efficiency both in using the substrate and in the device production.

Abstract:
A substrate stage and an empty-weight canceling mechanism that supports an empty weight of the substrate stage are made up of separate bodies. Accordingly, the size and weight of the substrate stage (a structure including the substrate stage) can be reduced, compared with the case where the substrate stage and the empty-weight canceling mechanism are integrally configured. Further, due to movement of an X coarse movement stage and a Y coarse movement stage by an X drive mechanism and a Y drive mechanism, the substrate stage is driven in an XY plane and also the empty-weight canceling mechanism that supports the empty weight of the substrate stage is driven. With this operation, the substrate stage can be driven without difficulty even when the substrate stage and the empty-weight canceling mechanism are configured of separate bodies.
