Abstract:
1. A computer storage medium containing a software routine that, when executed, causes a computer system to control a deposition chamber to perform a method for processing a substrate, comprising: seasoning a chamber by exposing the inside of the chamber to a first mixture comprising one or more organosilicon compounds and one or more oxidizing gases in the presence of RF power to deposit a seasoning layer on one or more interior surfaces of the chamber; and depositing a low dielectric constant layer on a substrate in the chamber by reacting a second mixture comprising one or more organosilicon compounds and one or more oxidizing gases in the presence of RF power, wherein a ratio of a total flow rate of the one or more organosilicon compounds of the first mixture into the chamber to a total flow rate of the one or more oxidizing gases of the first mixture into the chamber is lower than a ratio of a total flow rate of the one or more organosilicon compounds of the second mixture into the chamber to a total flow rate of the one or more oxidizing gases of the second mixture into the chamber.
