    Abstract: An X-ray exposure apparatus, for transferring a pattern of the mask (13) to a wafer (15), includes an X-ray source accommodating chamber (50); a mask chuck (14) for supporting the mask; a wafer chuck (16) for supporting the wafer; a stage (18) for moving the wafer chuck; a stage accommodating chamber (19) for accommodating therein the mask chuck, the wafer chuck and the stage; a barrel (5) for coupling the X-ray source accommodating chamber with the stage accommodating chamber, to define an X-ray projection passageway (30); a blocking window (6) provided in the X-ray projection passageway, for isolating the ambience in the X-ray accommodating chamber and the ambience in the stage accommodating chamber from each other; and a gas supply port (3) contributable to fill the stage accommodating chamber with a gas ambience of low X-ray absorption. The gas supply port opens to the X-ray projection passageway at a position between the blocking window and the mask supported by the mask chuck.

    Abstract: An exposure apparatus for transferring a pattern of an original (1) onto a workpiece (2) by using first light, includes a blocking member (4) for defining a rectangular exposure region on the workpiece. The blocking member (4) has a function for blocking the first light, wherein, through the exposure region defined by the blocking member (4), exposure for the pattern transfer can be effected. A detecting device (6) detects a positional deviation between the original (1) and the workpiece (2), by using second light different from the first light, wherein the blocking member (4) has a portion for transmitting the second light such that the detecting device (6) can detect the positional deviation with the second light passed through that portion of the blocking member.

    Abstract: A wafer chuck (2) usable with a semiconductor exposure apparatus (Fig.2A) wherein a mask and a semiconductor wafer (1) are placed in a vacuum ambience or a pressure-reduced gas ambience, and wherein the wafer (1) is exposed through the mask to radiation energy such as X-rays contained in a synchrotron radiation beam, by which the pattern of the mask is transferred onto the wafer (1). The wafer (1) is first attracted on the wafer supporting surface of the chuck (2) by vacuum attraction (21), and thereafter, the wafer (1) is attracted by electrostatic attraction force. Thereafter, the vacuum attraction is broken by supplying (24) a gas. Preferably Helium or other thermally conductive gas is admitted at this point. When the pattern of the mask is transferred onto the wafer (1), the wafer (1) is retained on the wafer supporting surface (20) by the electrostatic attraction force only. By this, the wafer supporting apparatus can correctly contact the wafer supporting surface (20) to the wafer (1) without being influenced by the undulation of the wafer (1). In addition, the heat produced in the wafer (1) during exposure can be removed efficiently by temperature controlled (23) water (11) supplied to the wafer supporting apparatus (2).
