Zusammenfassung:In an embodiment, a method for forming features for semiconductor processing. A first mandrel and a second mandrel are formed on a substrate. A first spacer is formed along a first sidewall of the first mandrel, and a second spacer is formed along a second sidewall of the second mandrel. A gap is defined between the first spacer and the second spacer. The gap is filled by a gap-filling material. In some examples, the gap-filling material includes a doped silicon material. In some examples, the first spacer and the second spacer each include a doped silicon material.
