High density TiN RF/DC PVD deposition with stress tuning
摘要:
Methods for depositing a layer on a substrate are provided herein. In some embodiments, a method of depositing a metal-containing layer on a substrate in a physical vapor deposition (PVD) chamber may include applying RF power at a VHF frequency to a target comprising a metal disposed in the PVD chamber above the substrate to form a plasma from a plasma-forming gas; optionally applying DC power to the target; sputtering metal atoms from the target using the plasma while maintaining a first pressure in the PVD chamber sufficient to ionize a predominant portion of the sputtered metal atoms; and controlling the potential on the substrate to be the same polarity as the ionized metal atoms to deposit a metal-containing layer on the substrate.
