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 10):
A method of forming a structure for etch masking comprising:\n forming second spacers on sidewalls of an etch mask having a window that exposes a connecting portion of a first spacer in the etch window, wherein the second spacers have a height greater than said first dielectric spacers; and removing the connecting portion of the first spacer, wherein remaining portions of the first spacers provide an etch mask, and the connecting portion removed from the first spacer provides an opening connecting a first trench proximate to mandrel structures and a second trench proximate to non-mandrel structures.
