摘要:
An X-ray transmitting window for use in X-ray lithography, for allowing transmission therethrough of X-rays from a vacuum ambience to a different ambience, is disclosed. The window includes an X-ray transmitting film; and a gasket material gas-tightly provided on at least one of opposite surfaces in a peripheral portion of the X-ray transmitting film, the gasket material having a Brinell hardness smaller than that of the X-ray transmitting film. The formed X-ray transmitting window is able to be sandwiched and fastened between a pair of flanges gas-tightly.
