Abstract:
A method for providing an etch mask for microelectronic processing that includes forming a material stack on a surface to be etched, wherein the material stack of at least a first material layer atop the surface to be etched for a base mandrel layer, and a second material layer atop the first material layer to provide a cap mandrel layer. If a following step, the material stack may be patterned and etched to provide double mandrel structures each including said base mandrel layer and said cap mandrel layer. A sidewall spacer is formed on sidewalls of the double mandrel structures.

Claim (Index 9):
The method of  claim 1 , wherein the sidewall spacer present on sidewalls of the double mandrel structure is a first sidewall spacer, wherein the method further comprises:\n removing the cap mandrel layer selectively to the base mandrel layer; forming second sidewall spacers on inner and outer sidewalls of the first sidewall spacer; removing the first sidewall spacer; and etching the surface to be etched using a mask provided by the second sidewall spacers and the base dielectric layer of the double mandrel structures.
