Abstract:
1. A method of forming a feature in a low-k dielectric film formed on a substrate, the method comprising: forming said low-k dielectric film on said substrate, said low-k dielectric film having a nominal dielectric constant less than a dielectric constant of SiO providing a mask on said low-k dielectric film; forming at least one feature in said low-k dielectric film by transferring a pattern in said mask to said low-k dielectric film; performing an ion implantation process, using at least one of a Boron ion and a Germanium ion, on a sidewall of said feature in said low-k dielectric film; metallizing said at least one feature in said low-k dielectric film, wherein said metallizing comprises at least one of depositing a metal seed layer within said feature, and performing a bulk metal fill deposition; and forming at least one of a metal boride. and a metal germanide.
