摘要: An apparatus for transferring a pattern of a mask onto a substrate with radiation light from a synchrotron radiation light source, includes a first mirror for collectively reflecting radiation light from the synchrotron radiation light source, and a second mirror for reflecting radiation light from the first mirror and for projecting the same to the mask. When a light ray advancing from a light emission point of the light source toward a center of a predetermined region of the mask, to be transferred to the substrate, is taken as a chief ray, when a normal to each of the first and second mirrors at an incidence position of a corresponding chief ray is taken as a Z axis, when a direction perpendicular to a plane defined by the Z axis of each mirror and a corresponding chief ray is taken as an X axis, and when a Y axis is taken along a direction perpendicular to the Z axis and X axis of each mirror, the first mirror has a reflection surface of a shape which is concave with respect to the X axis direction and concave with respect to the Y axis direction, while the second mirror has a reflection surface of a shape which is convex with respect to the Y axis direction.

摘要: A reflection type mask usable to print a pattern upon a semiconductor wafer by use of soft X-rays or otherwise is disclosed. A reflective surface is formed by a multilayered film which is formed on a substrate by layering different materials having different refractive indices in consideration of Bragg diffraction and Fresnel reflection. A non-reflective portion is formed on the reflecting surface to provide a desired pattern. Alternatively, a pattern comprising a multilayered structure may be formed upon a non-reflective substrate. The mask of the present invention assures pattern printing of high contrast.
