Abstract:
Some embodiments include methods of forming patterns. A first mask is formed over a material. The first mask has features extending therein and defines a first pattern. The first pattern has a first level of uniformity across a distribution of the features. A brush layer is formed across the first mask and within the features to narrow the features and create a second mask from the first mask. The second mask has a second level of uniformity across the narrowed features which is greater than the first level of uniformity. A pattern is transferred from the second mask into the material.
Abstract:
Some embodiments include methods of removing particles from over surfaces of semiconductor substrates. Liquid may be flowed across the surfaces and the particles. While the liquid is flowing, electrophoresis and/or electroosmosis may be utilized to enhance transport of the particles from the surfaces and into the liquid. In some embodiments, temperature, pH and/or ionic strength within the liquid may be altered to assist in the removal of the particles from over the surfaces of the substrates.
Abstract:
A method of mitigating asymmetric lens heating in photolithographically patterning a photo-imageable material using a reticle includes determining where first hot spot locations are expected to occur on a lens when using a reticle to pattern a photo-imageable material. The reticle is then fabricated to include non-printing features within a non-printing region of the reticle which generate additional hot spot locations on the lens when using the reticle to pattern the photo-imageable material. Other implementations are contemplated, including reticles which may be independent of method of use or fabrication.
Abstract:
Some embodiments include methods of forming patterns utilizing copolymer. A main body of copolymer may be formed across a substrate, and self-assembly of the copolymer may be induced to form a pattern of structures across the substrate. A uniform thickness throughout the main body of the copolymer may be maintained during the inducement of the self-assembly. In some embodiments, the uniform thickness may be maintained through utilization of a wall surrounding the main body of copolymer to impede dispersal of the copolymer from the main body. In some embodiments, the uniform thickness may be maintained through utilization of a volume of copolymer in fluid communication with the main body of copolymer.

Abstract:
Block copolymers can be self-assembled and used in methods as described herein for sub-lithographic patterning, for example. The block copolymers can be diblock copolymers, triblock copolymers, multiblock copolymers, or combinations thereof. Such methods can be useful for making devices that include, for example, sub-lithographic conductive lines.
