Abstract

PURPOSE:To reduce the time required for X-ray exposure as well as to imprve the accuracy in positioning by a method wherein the surface of a wafer to be exposed is divided into a plurality of rectangular regions having the same shape and a process, wherein a plurality of rectangular regions aparting at least a rectangular region are irradiated by the X-rays, is repeated. CONSTITUTION:The area whereon patterning will be performed on the wafer is divided into square regions A, B, C and D. First, four A regions are exposed by X-rays at the same time, then the four B regions adjoining said A regions are exposed simultaneously and subsequently, regions C and D are exposed in the same manner and the whole surface of the wafer is exposed by the X-rays. An X-ray exposing device is consisted of four X-ray sources 1, 2,... (two sources 1 and 2 only are shown in the diagram), a beryllium window 4 fixed on a retaining frame 5 and a shielding wall 3. When such an X-ray method as abovementioned is adopted, positionary deformed wafer can be correctly positoned in each process of exposure and the area of a region to be exposed by the X-ray irradiation becomes small, thereby enabling to reduce the distance between beryllium window 4 and a mask 6 a nd the attenuation of the X-ray intensity can be inhibited.
