摘要:
Methods are provided for processing a substrate for depositing an adhesion layer having a low dielectric constant between two low k dielectric layers. In one aspect, the invention provides a method for processing a substrate including introducing an organosilicon compound and an oxidizing gas at a first ratio of organosilicon compound to oxidizing gas into the processing chamber, generating a plasma of the oxidizing gas and the organosilicon compound to form an initiation layer on a barrier layer comprising at least silicon and carbon, introducing the organosilicon compound and the oxidizing gas at a second ratio of organosilicon compound to oxidizing gas greater than the first ratio into the processing chamber, and depositing a first dielectric layer adjacent the dielectric initiation layer.

摘要:
A method for seasoning a chamber and depositing a low dielectric constant layer on a substrate in the chamber is provided. In one aspect, the method includes seasoning the chamber with a first mixture comprising one or more organosilicon compounds and one or more oxidizing gases and depositing a low dielectric constant layer on a substrate in the chamber from a second mixture comprising one or more organosilicon compounds and one or more oxidizing gases, wherein a ratio of the total flow rate of the organosilicon compounds to the total flow rate of the oxidizing gases in the first mixture is lower than the total flow rate of the organosilicon compounds to the total flow rate of the oxidizing gases in the second mixture.
