Method to improve the roughness of metal deposition on low-k material |
摘要 |
A new method is provided to treat the surface of a low-k material. The invention is specifically aimed at the improvement of the TaN barrier layer that is used in the deposition of a dual damascene structure. The invention uses e-beam exposure to improve the barrier metal (PVD TaN) properties for copper and low-k applications.
