A coil is wound via an electrically insulating member within a slot of a stator core of an electromagnetic motor which is formed of a stator and a rotor. Groove portions are formed to oppose one another in respective opposing portions of a slot opening portion side of the electrically insulating member. An electrically insulating sheet is disposed by being inserted into the pair of groove portions.

An exposure apparatus exposes a substrate with an exposure light through an exposure liquid. The exposure apparatus includes an optical element from which the exposure light exits; a stage which is movable on the light-exit side of the optical element; a certain member which is provided on the stage; and a vibration generator which vibrates the certain member to apply vibration to the liquid in the liquid immersion space formed on the certain member. It is possible to suppress the deterioration of the performance which would be otherwise caused by any contamination.

Stopper mechanisms keep a wafer table and a measurement table from moving closer than a predetermined distance, and the blocking by the stopper mechanisms can also be released by a drive mechanism. Therefore, for example, in the case X-axis stators are driven independently, even if at least one of the two tables go out of control, the stopper mechanisms can keep the tables from coming into contact with each other, and for example, in the case the tables are to be in a state closer than the predetermined distance, by a release mechanism that releases the blocking of the stopper mechanisms, the tables can approach each other without the stopper mechanisms interfering.

A stage device includes a switching device that switches between a first state in which a stage can move along a first movement reference surface, and a second state in which the stage can move along a second movement reference surface. The stage device can have first and second stages, and the switching device can switch both stages between the first and second states, such that the first stage is switched to the first movement reference surface while the second stage is switched to the second movement reference surface and vice-versa. Because of this, even if the first movement reference surface is formed on a first reference member (e.g., a holding plate) and the second reference surface is formed on a second reference member (e.g., guides), no problems are generated due to movement of the first and second stages. Compared to a case on which the first and second movement reference surfaces are formed on a single reference member, the first reference member can be made smaller. Therefore, difficulty of processing the reference surfaces can be overcome because it is easier to precisely process smaller surfaces.

A pair of connecting wire hooks are disposed on both sides of a nozzle receiving groove in an extended slot space (a first extended space) to sandwich an extended portion of an extended virtual space (a third extended space). In this configuration, the pair of connecting wire hooks are not located within the third extended space. Thus, in the stator for rotary electric machine, the space factor of the winding portion may be increased in a situation where the connecting wire hook is disposed within the first extended space.

A stator for rotary electric machines is provided, in which a volume occupied by winding portions may be increased and a connecting wire may readily be engaged to prevent from coming off. A plurality of connecting wire engaging hooks 23, with which the connecting wire extending from the winding portion is engaged, are respectively disposed in the vicinity of border portions between a plurality of magnetic pole sections 11 and a yoke 9, corresponding to the magnetic pole sections 11. A mounting location of a connector 29 on a circuit substrate 7 is determined so that all of ends of a plurality of terminal conductors of the connector may be located between adjoining two of the connecting wire engaging hooks 23. With this arrangement, all of the ends 31a of the plurality of terminal conductors 31 may be disposed between adjoining two of a plurality of the winding portions 3, and be spaced from the winding portions 3.
摘要:
An exposure apparatus is provided with a first member that can form liquid immersion with a first liquid so as to fill an optical path for exposure light with the first liquid, a second member that can form liquid immersion with a second liquid in a position distanced from the first member, and a vibration generator that imparts vibration to the second liquid between the predetermined member and the second member. The predetermined member is cleaned with the second liquid.
摘要:
Stage apparatus are disclosed for holding an object (e.g., substrate or reticle, for example) in a microlithography system, especially a system for performing microlithography in a vacuum environment. The stage apparatus provides movement of a stage (intended to hold the object) in X and Y directions of a guide plane. The stage is mounted to an arm member having at least first and second ends situated symmetrically relative to the stage. The ends include linear-motor movers that interact with corresponding stators, and include gas bearings on surfaces that slide relative to other surfaces as the stage is moved within the guide plane. The linear-motor movers can be one- or two-dimensional movers and desirably allow &thgr;-direction motion of the stage. Other configurations include guide members and sliders that undergo sliding motion relative to the guide members via non-contacting gas bearings. The sliders can be driven by a combination of a linear motor and a gas cylinder, the latter assisting the driving force by the linear motor during acceleration and deceleration of the stage.
