Exposure method, exposure apparatus, x-ray mask, semiconductor device and microstructure

摘要

An exposure method, an exposure apparatus, an X-ray mask and a resist for achieving enhanced resolution and throughput compared with those having been accomplished are provided and further a semiconductor device and a microstructure manufactured by using them are provided. According to the exposure method, X rays (2) emitted from an X-ray source (1) are radiated to a resist film (10) via an X-ray mask (8). A material constituting the resist film (10) is selected to have an average wavelength of X rays absorbed by the resist film (10) that is equal to or smaller than an average wavelength of X rays (2) radiated to the resist film (10).
