Sidewall image templates for directed self-assembly materials
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 st...

| description | 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. |
