发明名称 メモリセルおよび磁気メモリセル構造のアレイの形成方法、ならびに関連するメモリセルおよびメモリセル構造
摘要 Methods of forming memory cells, magnetic memory cell structures, and arrays of magnetic memory cell structures are disclosed. Embodiments of the methods include patterning a precursor structure to form a stepped structure including at least an upper discrete feature section and a lower feature section with a broader width, length, or both than the upper discrete feature section. The method uses patterning acts directed along a first axis, e.g., an x-axis, and then along a second axis, e.g., a y-axis, that is perpendicular to or about perpendicular to the first axis. The patterning acts may therefore allow for more unifoimity between a plurality of formed, neighboring cell core structures, even at dimensions below about thirty nanometers. Magnetic memory structures and memory cell arrays are also disclosed.
