METHOD OF PATTERNING A LOW-K DIELECTRIC FILM |
摘要 |
Methods of patterning low-k dielectric films are described. In an example, a method of patterning a low-k dielectric film involves forming and patterning a mask layer above a low-k dielectric layer, the low-k dielectric layer disposed above a substrate. The method also involves modifying exposed portions of the low-k dielectric layer with a nitrogen-free plasma process. The method also involves removing, with a remote plasma process, the modified portions of the low-k dielectric layer selective to the mask layer and unmodified portions of the low-k dielectric layer. |
