摘要： Methods and controllers for controlling focus of ultraviolet light produced by a lithographic imaging system, and apparatuses for forming an integrated circuit employing the same are provided. In an embodiment, a method includes providing a wafer having a resist film disposed thereon. The resist film is patterned through illumination of a lithography mask with ultraviolet light at an off-normal incidence angle with a first test pattern formed at a first pitch and a second test pattern formed at a second pitch different from the first pitch. Non-telecentricity induced shift of the first and second test patterns is measured to produce relative shift data using a measurement device. Focus of the ultraviolet light is adjusted based upon comparison of the relative shift data to a pre-determined correlation between the non-telecentricity induced shift of the first and second test patterns as a function of focus error.

摘要： In one example, a method includes forming a template having a plurality of elements above a process layer and forming spacers on sidewalls of the plurality of elements. Portions of the process layer are exposed between adjacent spacers. At least one of the plurality of elements is removed. A mask structure is formed from a directed self-assembly material over the exposed portions. The process layer is patterned using at least the mask structure as an etch mask.

摘要： A method includes forming a chemical guide layer above a process layer. A template having a plurality of elements is formed above the process layer. The chemical guide layer is disposed on at least portions of the process layer disposed between adjacent elements of the template. A directed self-assembly layer is formed over the chemical guide layer. The directed self-assembly layer has alternating etchable components and etch-resistant components. The etchable components of the directed self-assembly layer are removed. The process layer is patterned using the template and the etch-resistant components of the directed self-assembly layer as an etch mask.
