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 11):
The method of  claim 10 , wherein said forming the sidewall spacer comprises:\n depositing a spacer material layer using a conformal deposition process; and etching the spacer material layer with an anisotropic etch process to remove horizontally orientated portions of the spacer material layer, wherein vertically orientated portions of the spacer material layer remain to provide the sidewall spacer.
