Title: Method and device for transferring fine pattern
Inventor: TERASAWA TSUNEO
IPC: H01L21/027
Filed: 1991-09-20
Abstract: PURPOSE:To prevent the deterioration of a projected image caused by a proximity effect even when the degree of the spatial coherence is large by providing a reflecting mirror, the reflectivity of which at the central section is higher than that at the peripheral section, at the diaphragm position of an image forming optical system which transfers a pattern on a first substrate to a second substrate after reduction. CONSTITUTION:A convex mirror 7 is constituted in such a way that the period of a multilayered film is continuously changed so that the reflectivity of the mirror 7 at its peripheral section can become lower than that at its central section. Since the mirror 7 corresponds to the diaphragm position of a reflection type image forming optical system 10, the reflectivity distribution on the mirror acts as a spatial frequency filter and prevents the deterioration of a projected image caused by a proximity effect when a pattern is transferred. Therefore, even when an X-ray projection optical system is a spatially coherent system, the influence of interference between adjacent patterns can be reduced and pattern transfer can be performed with extremely high form accuracy.
