Abstract

We demonstrate nearly diffraction-limited printing of 0.2-μm features, using soft x rays of approximately 36-nm wavelength. An open-stencil transmission mask with minimum features of 4 μm was imaged by a twentyfold-reduction Schwarzschild-type objective onto silicon wafers coated with various e-beam resists. Implications for soft-x-ray projection lithography are discussed.
