Abstract
PURPOSE: To produce a Si mask for X-ray lithography by providing a high-concentration O2-implanted layer having a required concentration peak at an arbitrary depth in a Si substrate, depositing heavy metal films thereon and etching the substrate from its rear surface down to the O2-implanted layer.
