Organic low-dielectric constant films deposited by plasma enhanced chemical vapor deposition

摘要

A method of forming a low-dielectric constant film on a substrate. The method includes placing the substrate within a plasma processing chamber. Gas within the chamber is removed. A combination of hydrocarbon and hydrofluorocarbon gasses are flowed into the chamber. A high density plasma is created in the chamber. The high density plasma is extinguished. Finally, all gas is removed from the chamber. The method can additionally include a heating step after the film has been formed.
