Abstract:
A method of forming a structure for etch masking that includes forming first dielectric spacers on sidewalls of a plurality of mandrel structures and forming non-mandrel structures in space between adjacent first dielectric spacers. Second dielectric spacers are formed on sidewalls of an etch mask having a window that exposes a connecting portion of a centralized first dielectric spacer. The connecting portion of the centralized first dielectric spacer is removed. The mandrel structures and non-mandrel structures are removed selectively to the first dielectric spacers to provide an etch mask. The connecting portion removed from the centralized first dielectric spacer provides an opening connecting a first trench corresponding to the mandrel structures and a second trench corresponding to the non-mandrel structures.

Claim (Index 4):
The etch method of  claim 1 , wherein forming the first spacers on sidewalls of the mandrel structures comprises:\n conformally depositing a material layer for the spacers on the plurality of mandrel structures; and etching the material layer, wherein the horizontally orientated portions are removed, and the vertically orientated portions of the material layer remains to provide the first spacers.
