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 5):
The method of  claim 2 , wherein spacer mandrels comprise silicon nitride.
