    Abstract: A method of modifying an opening in a mask to achieve desired critical dimensions, the method including performing a pre-implant on the mask to implant the mask with a dopant material, wherein a material of the mask is densified and the opening is enlarged, directing a first radical beam at a first lateral side of the opening to deposit a layer of material on the first lateral side, and directing a second radical beam at a second lateral side of the opening opposite the first lateral side to deposit a layer of material on the second lateral side.

    Abstract: An etching and deposition system including a process chamber containing a platen for supporting a substrate, an reactive-ion etching (RIE) source adapted to produce an ion beam and to direct the ion beam into the process chamber for etching the substrate, a first plasma enhanced chemical vapor deposition (PECVD) source located on a first side of the RIE source, the first PECVD source adapted to produce a first radical beam and to direct the first radical beam into the process chamber for depositing a first material, and a second PECVD source located on a second side of the RIE source opposite the first side, the second PECVD source adapted to produce a second radical beam and to direct the second radical beam into the process chamber for depositing a second material.
