Abstract:
Embodiments described herein relate generally to methods for forming a mask for patterning a feature in semiconductor processing. In an embodiment, a dielectric layer is formed over a substrate. A mask is formed over the dielectric layer. Forming the mask includes depositing a first layer over the dielectric layer; implanting in a first implant process a dopant species through a patterned material and into the first layer at a first energy; after implanting in the first implant process, implanting in a second implant process the dopant species through the patterned material and into the first layer at a second energy greater than the first energy; and forming mask portions of the mask comprising selectively removing portions of the first layer that are not implanted with the dopant species.

Claim (Index 9):
A method for semiconductor processing, the method comprising:\n forming a first layer over a substrate; implanting a first region of the first layer with a dopant species, the implanted first region having a first depth and a first concentration of the dopant species; implanting a second region of the first layer with the dopant species through the implanted first region, the implanted second region having a second depth and a second concentration of the dopant species, the second depth being greater than the first depth, the first concentration being greater than the second concentration; and selectively etching the first layer to remove a third region of the first layer outside of the implanted first region and the implanted second region, wherein at least a portion of the implanted first region and the implanted second region remains after the selective etching.
