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 16):
The method of  claim 1 , wherein prior to forming the spin-on-carbon layer, the method further comprises:\n forming mandrels in spin-on-carbon layer on a second etch stop layer on an amorphous silicon layer on an etch stop layer on an oxide layer on a substrate; forming a conformal spacer layer on the mandrels in the spin-on-carbon layer; removing the mandrels and square etching the conformal spacer layer to form spacer mandrels on the second etch stop layer; transferring the spacer mandrels on the second etch stop layer to the amorphous silicon layer to form spacer mandrels on the etch stop layer and removing the second etch stop layer and portions of the amorphous silicon layer to expose the etch stop layer; forming a conformal oxide layer on the spacer mandrels on the etch stop layer; etching the conformal oxide layer to form oxide films on both sides of the spacer mandrels with a gap between adjacent oxide films; depositing a gapfill material in the gap to remove the gap; removing the amorphous silicon spacer mandrels leaving gaps between adjacent oxide films; and depositing a silicon nitride film in the gaps to remove the gaps.
