Abstract:
A scanning exposure apparatus wherein a portion of a pattern of an original is projected on to a substrate through a projection optical system (2) and wherein the original and the substrate are scanningly moved relatively to the projection optical system (2) whereby the pattern of the original is transferred on to the substrate. The apparatus includes an original stage (1) for holding the original, a base (9) for supporting the original stage (1), and a supporting system for supporting the base (9) at three positions, through dampers (11) and pillars (12).

Abstract:
A supporting device for supporting a member having an inside movable portion, includes a main frame (511) and a supporting reference plate (530) on which the member is to be placed. A plurality of driving mechanisms are disposed between the main frame and the supporting reference plate, each having a high-rigidity displacement providing element (540) and a low-rigidity supporting element (550) with a low damping factor, disposed in series. The supporting device has particular application with an attitude control device for an X-ray exposure apparatus.
Abstract:
A method of supporting or mounting a precision instrument for supporting a mask and a wafer in a vacuum container. It is particularly applicable to a SOR-X ray exposure apparatus wherein the mask and the wafer are disposed in a desired level of the reduced pressure, and exposure energy such as X-rays contained in synchrotron radiation is projected onto the wafer through the mask to print the pattern of the mask onto the wafer. In x-y-z coordinates with the x direction being vertical, the precision instrument in hung at at least two points which are spaced in the x direction, to the inside wall of the vacuum container. At one of the supporting points, the precision instrument is given latitude of x, y and z direction movement, and at the other supporting point, the precision instrument is fixed or is given a latitude only in the x direction. By this, when the vacuum container deforms by the difference between the internal and external pressures, the precision instrument can be supported correctly.
Abstract:
Disclosed is a moving mechanism which includes a reference structure having a guide surface (6), a movable portion (3) being movable along the guide surface, and an actuator (8) having a movable element (2) disposed at the movable portion side and at least two stators (1,1'), the stators being separated from each other and being moved by a reaction force produced as the movable portion is driven.
Abstract:
A method of manufacture of semiconductor devices wherein a radiation beam is projected from a synchrotron orbit radiation source into an ambience maintained substantially at a vacuum, wherein a first beam which is a portion of the radiation beam is directed to a wafer through a window effective to isolate the ambience to thereby print a circuit pattern on an X-ray sensitive layer on the wafer with the first beam, wherein an opening is formed at least in a portion of a support for supporting the window, wherein a second beam which is another portion of the radiation beam is extracted through the opening, and wherein, by using the second beam, any deviation of the first beam with respect to the wafer is detected and corrected.
