摘要:
A method for repairing damage to a silicon based low-k dielectric layer with organic compounds, where damage replaces a methyl attached to silicon with a hydroxyl attached to silicon is provided. A repair gas comprising CH4 gas is provided. The repair gas is formed into a plasma, while maintaining a pressure below 50 mTorr. Hydroxyl attached to silicon is replaced with methyl from the plasma formed by the repair gas.
