Abstract:
Methods of forming semiconductor devices comprising etching a hardmask and spin-on-carbon layer through an opening in a photoresist to expose a gapfill material. The photoresist, spin-on-carbon layer and gapfill material are removed. A new spin-on-carbon layer, hardmask and photoresist are formed with an opening over a spacer mandrel. The hardmask, spin-on-carbon layer are etched through the opening and the layers and spacer mandrel are removed. An etch stop layer and oxide layer are removed and a height of the spacer mandrel and gapfill material are reduced exposing portions of the substrate. The exposed portions of the substrate are fin etched and the layers removed.

Claim (Index 1):
A method of forming a semiconductor device, the method comprising:\n forming a spin-on-carbon layer, a hardmask and a photoresist on a film comprising alternating columns of spacer mandrels and gapfill materials with oxide films between, the photoresist having an opening over one of the gapfill materials; etching the hardmask and spin-on-carbon layer through the opening in the photoresist to expose a top of one of the gapfill materials; removing the spin-on-carbon layer, hardmask and gapfill material to leave a gap; forming a spin-on-carbon layer, a hardmask and a photoresist on the film comprising alternating columns of spacer mandrels, gapfill materials, oxide films and the gap, the photoresist having an opening over one of the spacer mandrels; etching the hardmask and spin-on carbon layer through the opening in the photoresist to expose a top of one of the spacer mandrels; removing the spin-on-carbon layer, hardmask and spacer mandrel to leave another gap; removing the oxide films to leave spacer mandrels and gapfill materials on an etch stop layer on an oxide layer on a substrate; etching to remove the etch stop layer and the oxide layer not covered by the spacer mandrels or gapfill materials and reducing a height of the spacer mandrels and gapfill materials to expose portions of the substrate; and fin etching the exposed portions of the substrate and removing the remaining spacer mandrels, gapfill materials, etch stop layer and oxide layer.
