摘要:
A method for depositing a low dielectric constant film by flowing a oxidizing gas into a processing chamber, flowing an organosilicon compound from a bulk storage container through a digital liquid flow meter at an organosilicon flow rate to a vaporization injection valve, vaporizing the organosilicon compound and flowing the organosilicon compound and a carrier gas into the processing chamber, maintaining the organosilicon flow rate to deposit an initiation layer, flowing a porogen compound from a bulk storage container through a digital liquid flow meter at a porogen flow rate to a vaporization injection valve, vaporizing the porogen compound and flowing the porogen compound and a carrier gas into the processing chamber, increasing the organosilicon flow rate and the porogen flow rate while depositing a transition layer, and maintaining a second organosilicon flow rate and a second porogen flow rate to deposit a porogen containing organosilicate dielectric layer.
