Abstract:
An example embodiment may include a method for defining patterns for conductive paths in a dielectric layer. The method may include (a) forming a mask layer on the dielectric layer, (b) forming on the mask layer a set of longitudinally and parallel extending mask features, each mask feature including a mandrel having a pair of side wall spacers, the mask features being spaced apart such that gaps are formed between the mask features, (c) depositing an organic spin-on layer covering the set of mask features and filling the gaps, (d) etching a first trench in the organic spin-on layer, the first trench extending across at least a subset of the gaps and exposing the mask layer, and (e) depositing in a spin-on process a planarization layer covering the organic spin-on layer and filling the first trench.

Claim (Index 2):
The method according to  claim 1 , further comprising, subsequent to reducing the thickness of the planarization layer and the organic spin-on layer:\n depositing an organic spin-on layer covering the set of mask features and each first block mask, etching a second trench in the organic spin-on layer, the second trench extending across and exposing at least a subset of mandrels, and further etching each mandrel of the at least a subset of mandrels in the second trench, selective to the organic spin-on layer, to expose the mask layer, depositing in a spin-on process a planarization layer covering the organic spin-on layer and filling the second trench, reducing a thickness of the planarization layer and the organic spin-on layer by etching until upper surfaces of the mask features are exposed, thereby forming, of remaining material of the planarization layer, a discrete second block mask along each mandrel of the at least a subset of mandrels, removing the subset of mandrels, selectively to each second block mask, thereby exposing the mask layer between each pair of side wall spacers, and etching the mask layer between each pair of side wall spacers, wherein each second block mask act as an etch mask, thereby forming a second set of trenches in the mask layer, at least one of the trenches being interrupted in a longitudinal direction.
