摘要:
This invention discloses an apparatus having a base and a movable body which is driven to move along the base. The apparatus includes a generator configured to generate a driving signal for the movable body, a temperature adjusting mechanism configured to adjust temperature of the base, and a controller configured to control a manipulated variable for the temperature control mechanism based on the generated driving signal.

A stage apparatus includes a base, a stage movable on the base in first and second directions, a first member movable relative to the base in the first direction, and a second member movable relative to the base in the second direction. The first member is placed on the second member. With this arrangement, drive reaction-forces generated due to movement of the stage can be canceled by moving the first and second members, resulting in a smaller space needed for accommodating a canceling mechanism.

An object holding apparatus including a chuck for holding an object, a holder configured to hold the chuck, a generator provided in the holder and configured to generate a field related to an attraction force, a member provided in the chuck and configured to be attracted by the generator in accordance with the field, and a support configured to support one of the generator and the member. The support is configured to allow the one to move toward the other and away from the other, and the support includes a leaf spring.
摘要:
Disclosed is technology for holding a substrate and, specifically, an object holding apparatus including a chuck for holding an object, a holding unit for holding the chuck, a generating unit provided in the holding unit, for generating a field related to an attraction force, a member provided in the chuck and attracted by the generating unit in accordance with the field, and a supporting unit for supporting one of the generating unit and the member, for movement at least in a direction nearing the other and in a direction away from the other.

A stage device includes a movable stage, a base which supports the stage, and a mass body which moves to cancel a reaction force acting on the base as the stage moves. The base has a plurality of surfaces, and the stage and mass body are supported by different ones of the surfaces of the base. In addition, when the mass body is arranged in the base, the stage device can be more downsized.

摘要:
A substrate holding apparatus contacts an undersurface of a substrate and holds the substrate. At least a portion of a top surface of the substrate is to be immersed in liquid. The apparatus includes a chuck unit to attract the substrate and a preventing system to prevent the liquid from reaching the undersurface of the substrate.
