Abstract:
Methods of patterning metallization lines having variable widths in a metallization layer. A first mandrel layer is formed over a mask layer, with the mask layer overlying a second mandrel layer. The first mandrel layer is etched to form mandrel lines that have variable widths. The first non-mandrel trenches are etched in the mask layer, where the non-mandrel trenches have variable widths. The first mandrel lines are used to etch mandrel trenches in the mask layer, so that the mandrel lines and first non-mandrel lines define a mandrel pattern. The second mandrel layer is etched according to the mandrel pattern to form second mandrel lines, with the second mandrel lines having the variable widths of the plurality of first mandrel lines and the variable widths of the plurality of non-mandrel trenches.

Claim (Index 14):
The method of  claim 12  wherein forming at least one cut in the one line of the second non-mandrel pattern comprises:\n depositing a gapfill material over the spacer material; \n recessing the gapfill material to expose portions of the spacer material disposed over the second mandrel lines; \n forming a patterned lithography stack over the gapfill material and the spacer material, the patterned lithography stack having at least one opening that exposes a portion of the gapfill material corresponding to the at least one cut in the one line of the second non-mandrel pattern; \n removing the exposed portion of the gapfill material to form a cut in the gapfill material; and \n depositing the spacer material in the cut in the gapfill material, the spacer material merging with the second mandrel spacers and defining the at least one cut in the one line of the second non-mandrel pattern.
