    摘要: Methods for etching devices used for lithography. In one aspect, a method includes etching, in a single etch, a first region and a second region on a substrate. The first region is to attenuate an intensity of the zero diffraction order of a radiation for patterning of a microelectronic device to a first extent. The second region is to attenuate the intensity of the zero diffraction order of the radiation to a second extent. The second extent being sufficiently different from the first extent to improve a quality of the patterned microelectronic device.

    摘要: A composite patterning technique may include three lithography processes. A first lithography process forms a periodic pattern of alternating continuous lines of substantially equal width and spaces on a first photoresist. A second lithography process uses a non-interference lithography technique to break continuity of the patterned lines and form portions of desired integrated circuit features. The first photoresist may be developed. A second photoresist is formed over the first photoresist. A third lithography process uses a non-interference lithography technique to expose a pattern on the second photoresist and form remaining desired features of an integrated circuit pattern.

    摘要: A technique for introducing variable phase delay across portions of a spatially coherent light beam, such as a laser, without changing the focal length of the portions of the beam. A fly's-eye lens array is utilized to distribute the light for a more uniform illumination, but different length air gaps are introduced in the lens elements to provide a variable delay of portions of the beam. In a second scheme, a set of prisms is positioned in the path of the laser beam, in which the shape of the prism introduces variable phase delay across the cross-section of the beam.
