Abstract
Some embodiments include methods of forming electrically conductive lines. Photoresist features are formed over a substrate, with at least one of the photoresist features having a narrowed region. The photoresist features are trimmed, which punches through the narrowed region to form a gap. Spacers are formed along sidewalls of the photoresist features. Two of the spacers merge within the gap. The photoresist features are removed to leave a pattern comprising the spacers. The pattern is extended into the substrate to form a plurality of recesses within the substrate. Electrically conductive material is formed within the recesses to create the electrically conductive lines. Some embodiments include semiconductor constructions having a plurality of lines over a semiconductor substrate. Two of the lines are adjacent to one another and are substantially parallel to one another except in a region wherein said two of the lines merge into one another.
