Disclosed is a stage leveling device for a high-performance mask aligner, having enhanced leveling maintenance and, in particular, a novel technology of preventing leveling misalignment by firmly fixing a leveling-completed wafer stage. A conventional leveling device fixes a leveling-completed wafer stage by partially pressing side surfaces of a leveling rod and thus the leveling is misaligned due to deviations (errors) occurring while the leveling rod is moved upward and downward and leftward and rightward, and slip occurs due to a weak fixing strength of the leveling rod and thus the weight of the wafer (sample) that can be leveled to the maximum extent is decreased. To address the problems described above, according to the present invention, when a locking ring (80) inserted at an outer side of a leveling rod (40;41) maintains an inclined state, locking is performed such that an inner circumferential surface of the locking ring fixes opposite sides of the leveling rod by applying pressure thereto and, when the locking ring maintains a horizontal state, unlocking is performed such that the inner circumferential surface of the locking ring is spaced apart from the leveling rod.

There is provided a pattern forming apparatus which transfers a paste to a predetermined position of a pattern forming object fixed to a table through a pattern forming mask having opening portions at predetermined positions using a discharge mechanism part. To realize a pattern forming which allows the stable forming of a fine pattern with high accuracy and allows the paste to be surely filled into fine through holes, a corner portion of a distal end of the discharge mechanism part in contact with the pattern forming mask is formed into a concave shape, and a surface of the distal end portion of the discharge mechanism part including the concave shaped portion is covered with a film having liquid repellency so that the rolling of the paste is accelerated in a region formed by the concave shaped portion to form a fine pattern with high accuracy.

An exposure apparatus which prevents the damage due to the liquid having flowed out from spreading and enables satisfactory performances of the exposure processes and the measurement processes is provided. An exposure apparatus (EX) includes a movable table (PT), a base member (41) having an upper surface (41 A) that guides the movement of the table (PT), and a detecting device (60) that detects whether there is a liquid on the upper surface (41A) of the base member (41).

摘要:
A part of a plate (50) of a predetermined shape detachably mounted on a moving body (WST) is detected by an alignment system (ALG) while the position of the moving body is measured by a measurement unit (18 or the like) that sets a movement coordinate system of the movement body, and based on the detection results and the measurement results of the measurement unit corresponding to the detection results, position information of an outer periphery edge of the plate (50) is obtained. Therefore, even if there are no alignment marks (fiducial marks) on the moving body (WST) for position measurement, the position of the plate, or in other words, the position of the moving body can be controlled on the movement coordinate system set by the measurement unit, based on the position information of the outer periphery edge of the plate.

The kinematic coupling of the present invention may comprise a wafer carrier base plate (100) comprising a first material, and a mounting plate (102) and multiple contact components (104). The mounting plate (102) has multiple recesses (118) corresponding to the number of contacts (104), each recess (118) provided with a protrusion (116) for engaging the bore of a respective contact component (104). The contact component (104) comprises a second material having a lower coefficient of friction than the first material. The contact component (104) may comprise an interior surface (108) with a contact surface (106) that converges as the interior surface (108) deepens. The contact component (104) may be provided to the base plate (100) as part of an over-molding, snap-in-place, staking, ultrasonic weld, or adhesive operation and held in place by mechanical interlocking.
