A method according to  claim 7 , wherein the protection cover is detached from the mask at a position for exposure. claim 7 9. A method according to  claim 7 , wherein the mask has a multilayered film reflection type mirror and the pattern is formed on the multilayered film reflection type mirror, and wherein the pattern absorbs the X-rays. claim 7 10. A device manufacturing method comprising the steps of: attaching a protection cover to a mask at an attaching position;  detaching the protection cover from the mask at a position different from the attaching position;  executing alignment between a member to be exposed and the mask from which the protection cover has been detached; and  transferring a pattern onto the member to be exposed by exposure with X-rays by using the mask from which the protection cover has been detached, to manufacture a device using the member. 11. A method according to  claim 10 , wherein the protection cover is detached from the mask at a position for exposure. claim 10 12. A method according to  claim 10 , wherein the mask has a multilayered film reflection type mirror and the pattern is formed on the multilayered film reflection type mirror, and wherein the pattern absorbs the X-rays. claim 10 13. An exposure method for transferring a pattern of a mask onto a member to be exposed, said method comprising the steps of: providing the mask, which includes (i) a multilayered film reflection type mirror, (ii) a pattern, formed on the multilayered film reflection type mirror, which absorbs X-rays, and (iii) a protection cover covering at least a portion of the multilayered film reflection type mirror, and structured to be detachable from the multilayered film reflection type mirror;  executing alignment between the member to be exposed and the mask while the protection cover is detached from the mask; and  executing exposure with X-rays while the protection cover is detached from the mask. 14. An exposure apparatus comprising: means for holding a mask that includes (i) a multilayered film reflection type mirror, (ii) a pattern, formed on the multilayered film reflection type mirror, which absorbs X-rays, and (iii) a protection cover covering at least a portion of the multilayered film reflection type mirror, and structured to be detachable from the multilayered film reflection type mirror;  means for holding a member to be exposed; and  means for detaching the protection cover from the mask, wherein alignment between the mask and the member is executed while the protection cover is detached from the mask, and exposure with X-rays is executed while the protection cover is detached from the mask. 15. A device manufacturing method comprising the steps of: providing a mask which comprises (i) a multilayered film reflection type mirror, (ii) a pattern, formed on the multilayered film reflection type mirror, which absorbs X-rays, and (iii) a protection cover covering at least a portion of the multilayered film reflection type mirror, and structured to be detachable from the multilayered film reflection type mirror;  executing alignment between a member to be exposed and the mask while the protection cover is detached from the mask; and  transferring the pattern onto the member to be exposed with X-rays while the protection cover is detached from the mask, to manufacture a device using the member. 16. An exposure method for transferring a pattern of a mask onto a member to be exposed, said method comprising the steps of: preparing for exposure while the mask is attached with a protection member;  executing alignment between the member to be exposed and the mask while the protection member is detached from the mask; and  executing exposure with X-rays while the mask is detached from the protection member. 17. A method according to  claim 16 , wherein the mask has a multilayered film reflection type mirror and the pattern is formed on the multilayered film reflection type mirror, and wherein the pattern absorbs the X-rays. claim 16 18. A device manufacturing method comprising the steps of: preparing for exposure while a mask is attached with a protection member;  executing alignment between a member to be exposed and the mask while the protection member is detached from the mask; and  transferring a pattern of the mask onto the member to be exposed while the mask is detached from the protection member, so as to manufacture a device using the member. 19. A method according to  claim 16 , wherein the mask has a multilayered film reflection type mirror and the pattern is formed on the multilayered film reflection type mirror, and wherein the pattern absorbs the X-rays. claim 16 20. An exposure apparatus comprising: means for holding a mask;  means for holding a member to be exposed; and  means for detaching a protection cover from the mask,  wherein alignment between the mask and the member is executed while the protection cover is detached from the mask, and exposure with X-rays is executed while the protection cover is detached from the mask. 21. An exposure apparatus comprising: means for holding a mask;  means for holding a member to be exposed; and  means for detaching the mask from a protection member,  wherein alignment between the mask and the member to be exposed is executed while the mask is detached from the protection member, and exposure with X-rays is executed while the mask is detached from the protection member. 22. A method for exposing a member to be exposed with a pattern on a mask, said method comprising steps of: performing preparation for and exposure operation by covering the pattern with a protection member; and  performing an alignment of the member to be exposed and the mask without covering the pattern with the protection member and performing the exposure operation by using X-rays. 23. A device manufacturing method comprising steps of: performing preparation for an exposure operation by covering the pattern with a protection member;  performing an alignment of the member to be exposed and the mask without covering the pattern with the protection member and performing the exposure operation by using X-rays; and  developing the member to be exposed. 24. An exposure apparatus for exposing a member to be exposed with a pattern on a mask, said apparatus comprising: a mirror for guiding X-rays to the mask;  a first state for holding the mask;  a second state for holding the member to be exposed; and  means for separating the mask and a protection member which covers the pattern on the mask,  wherein an alignment of the member to be exposed and the mask is performed without covering the pattern with the protection member and the member to be exposed is exposed by the X-rays.
