Abstract:
1. A method of processing a substrate, comprising: flowing one or more organosilicon compounds and one or more oxidizing gases into a chamber; depositing a low dielectric constant film comprising silicon, carbon, and oxygen on a substrate in the chamber in the presence of RF power; increasing a total flow rate of the one of more oxidizing gases into the chamber after depositing the low dielectric constant film; decreasing a total flow rate of the one or more organosilicon compounds into the chamber after depositing the low dielectric constant film; and then depositing an oxide rich cap on the low dielectric constant film in the chamber in the presence of RF power, while maintaining the total flow rate of the one or more oxidizing gases and the total flow rate of the one or more organosilicon compounds.
