Patent ID: 7981699

Claim:
A method for providing a tuned repair for 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, comprising: providing a precursor gas, comprising: a first repair agent represented as Si—(R) x (OR′) y , where y≧1 and x+y=4, and wherein R is an alkyl or aryl group and R′ is an alkyl or aryl group; and a second repair agent represented as Si—(R) x (OR′) y R″, where y≧1 and x+y=3, and wherein R is an alkyl or aryl group and R′ is an alkyl or aryl group, and R′ is of a group that reduces interfacial surface tension between a wet clean chemical and the low-k dielectric; and bonding some of the first repair agent and second repair agent to the low-k dielectric to form a monolayer of the first repair agent and the second repair agent.
