A circulating system (10) for cooling a shaft-type linear motor (12) is provided herein. The motor (12) includes a magnet array (22) and a coil assembly (16). The circulating system (10) includes coil housing (36) that encircles the coil assembly (16) and defines a fluid passageway (46) between the coil housing (36) and the coil assembly (16). Fluid (44) from a fluid source (42) is forced through an inlet (38) into the fluid passageway (46). The flow rate of the fluid (44) is controlled to maintain an outer surface (111) of the coil housing (36) at a set temperature to control the effect of the motor (12) on the surrounding environment and the surrounding components.

On a sample stand having a chip levelling mechanism for amending the exposure plane of a wafer in relation to the image plane of a projection lens, a dynamic damper is provided for assigning to a holder table the appropriate rigidity in the moving direction of the holder table.
摘要:
A supporting apparatus for supporting a table having N degrees of freedom, where N is an integer greater than one. The apparatus includes a stage and a leaf spring mounted on the stage. The spring initially contacts the table at a contact point and has a coefficient of elasticity greater in the horizontal direction and smaller in the vertical direction. The spring also has a characteristic of positive rigidity. A pair of permanent magnets are mounted in an area between the stage and table in a vertical direction for counterbalancing the characteristic of positive rigidity of the leaf spring.

摘要:
An exposure apparatus and an exposure method capable of performing high-precision superposition exposure by preventing the thermal deformation of a position measurement target, for controlling positioning of a moved member, from influencing the correction of an error in the positioning of the moved member. The exposure apparatus projects an image of a pattern, formed on a mask, onto a photosensitive substrate through a projection optical system. A stage, on which the photosensitive substrate is mounted, is movable in at least X-axis and Y-axis directions in an imaging plane of the projection optical system. Position measuring devices measure the position of the stage in each of the two directions and are disposed so that the Abbe error is substantially zero with respect to the position at which the substrate is exposed to the pattern image. A pattern detector is disposed on a measuring axis of the position measuring devices with respect to one of the two directions to optically detect an alignment pattern formed on the photosensitive substrate. A rotation measuring device measures the amount of rotation of a measurement target of the position measuring devices with respect to the X- and Y-axis directions, and a controller controls the position and the amount of rotation of the stage on the basis of the amount of rotation measured by the rotation measuring device, the positions measured by the position measuring devices, and information regarding the position of the pattern detected by the pattern detector.
摘要:
A powder coating composition in which epoxy resin particles and curing agent particles are uniformly distributed is prepared by heating a specific powdery blend of (a) at least one crystalline epoxy resin, (b) at least one crystalline curing agent and (c) at least one non-crystalline epoxy resin and/or at least one non-crystalline curing agent at a specific temperature so that the crystalline particles are bonded with each other with the non-crystalline substance serving as a binder.
摘要:
An exposure apparatus is an exposure apparatus that exposes a substrate by filling a liquid between a projection optical system and the substrate, and projecting a pattern image onto the substrate via the projection optical system and the liquid, wherein the projection optical system has a first group comprising an optical member that contacts the liquid, and a second group that differs from that first group; the first group is supported by a first support member; and the second group is separated from the first group and is supported by the second support member that differs from the first support member.

A magnetic guide apparatus includes a guide member that has a guide plane provided along a first direction, and a moving body that has a facing plane facing the guide plane to be spaced apart from the guide plane. Magnetic attractive force is permitted to operate between the guide plane and the facing plane, such that the moving body is moved along the first direction while movement to a second direction, which is orthogonal to the first direction and parallel to the guide plane, is controlled. A first groove section is formed along the first direction on the guide plane and a second groove section is formed along the first direction so as to face the first groove section on the facing plane.

An edge exposing apparatus includes a photo detector and a lighting time measuring circuit for detecting a decrease in performance of light source units. The lighting time measuring circuit detects a ready state ((stabilization of luminous intensity) of the light source units, for example by measuring a lighting time for a startup (switch-on) of the light source units. When the measuring circuit detects a preset lighting time, or when the photo detector detects a luminous intensity below a preset value, the light source units are determined to have lowered performance, and are switched off. When a decrease in performance of one unit is detected, a replacement light source unit is started while continuing edge exposure with one or more other light source unit(s). When a ready state is detected, the edge exposure with the one light source unit is terminated (switch-off), and edge exposure is performed with the replacement light source unit.
