    Abstract: Mask pattern formation is facilitated by: providing a mask structure including at least one sacrificial spacing structure disposed above a substrate structure; disposing a spacer layer conformally over the mask structure; selectively removing the spacer layer, leaving, at least in part, sidewall spacers along sidewalls of the at least one sacrificial spacing structure, and providing at least one additional sacrificial spacer over the substrate structure, one additional sacrificial spacer of the at least one additional sacrificial spacer being disposed in set spaced relation to the at least one sacrificial spacing structure; and removing the at least one sacrificial spacing structure, leaving the sidewall spacers and the at least one additional sacrificial spacer over the substrate structure as part of a mask pattern.

    Abstract translation: 通过以下方式促进掩模图案形成:提供掩模结构,其包括设置在基板结构上方的至少一个牺牲间隔结构; 将掩模层保形地设置在掩模结构上; 选择性地去除间隔层,至少部分地留下沿着至少一个牺牲间隔结构的侧壁的侧壁间隔物,并且在衬底结构上方提供至少一个额外的牺牲间隔物,该至少一个额外的牺牲隔离物 间隔件与所述至少一个牺牲间隔结构设置成间隔开的关系; 以及去除所述至少一个牺牲间隔结构,将所述侧壁间隔物和所述至少一个另外的牺牲隔离物留在所述衬底结构上作为掩模图案的一部分。
