20140193980 | PATTERNED LINE END SPACE - One or more techniques or systems for forming a line end space structure are provided herein. In some embodiments, a first patterned second hard mask (HM) region is formed above a first HM region. In some embodiments, a first sacrificial HM region and a second sacrificial HM region are formed above at least one of the first patterned second HM region or the first HM region. Photo resist (PR) is patterned above the second sacrificial HM region, and a spacer region is deposited above the PR and second sacrificial HM region. In some embodiments, at least some of at least one of the spacer region, the PR, or the respective sacrificial HMs is removed. Accordingly, first patterned second hard mask (HM) region is patterned, thus forming the line end space structure associated with an end-to-end space. | 07-10-2014 |
