    摘要: Some embodiments include methods of forming patterns. A semiconductor substrate is formed to comprise an electrically insulative material over a set of electrically conductive structures. An interconnect region is defined across the electrically conductive structures, and regions on opposing sides of the interconnect region are defined as secondary regions. A two-dimensional array of features is formed over the electrically insulative material. The two-dimensional array extends across the interconnect region and across the secondary regions. A pattern of the two-dimensional array is transferred through the electrically insulative material of the interconnect region to form contact openings that extend through the electrically insulative material and to the electrically conductive structures, and no portions of the two-dimensional array of the secondary regions is transferred into the electrically insulative material.

    摘要: Photolithographic apparatus and methods are disclosed. One such apparatus includes an optical path configured to provide a first diffraction pattern in a portion of an optical system and to provide a second diffraction pattern to the portion of the optical system after providing the first diffraction pattern. Meanwhile, one such method includes providing a first diffraction pattern onto a portion of an optical system, wherein a semiconductor article is imaged using the first diffraction pattern. A second diffraction pattern is also provided onto the portion of the optical system, but the second diffraction pattern is not used to image the semiconductor article.

    摘要: Some embodiments include system and methods to obtain information for adjusting variations in features formed on a substrate of a semiconductor device. Such methods can include determining a first pupil in an illumination system used to form a first feature, and determining a second pupil used to form a second feature. The methods can also include determining a pupil portion belonging to only one of the pupils, and generating a modified pupil portion from the pupil portion. Information associated with the modified pupil portion can be obtained for controlling a portion of a projection lens assembly of an illumination system. Other embodiments are described.
