    摘要: A lithography apparatus with an optical fiber module includes: a light source, a photo mask positioned under the light source, a lens positioned under the photo mask, a wafer stage positioned under the lens for supporting the wafer, wherein the wafer includes a dry film. The lithography apparatus further includes an optical fiber module having a front surface facing away from the lens, wherein a gap is between the front surface and the dry film and the gap is smaller than the wavelength of the light source. The DUV (deep ultraviolet) can pass through the optical fiber module. The present invention features a gap smaller than the wavelength of the light source, creating a near-field effect with improved resolution.

    摘要: A patterning method has a mask layer and undoped patterns sequentially formed on a target layer. A doping process is performed to surfaces of the undoped patterns to form doped patterns from the surfaces of the undoped patterns. A material is filled in the gaps between the doped patterns. A portion of the doped patterns are then removed to expose the top surfaces of the remaining undoped patterns. The material and the exposed undoped patterns are removed. A portion of the mask layer is removed using the remaining doped patterns as a mask to form a first pattern on the mask layer. A portion of the target layer is removed using the mask layer having the first pattern thereon as a mask so as to form on the target layer a second pattern complementary to the first pattern.
