Abstract:
1. A method of treating a low dielectric constant film on a plurality of substrates, comprising: disposing said plurality of substrates in a batch processing system including a process chamber, said dielectric film on the plurality of substrates having a dielectric constant value less than the dielectric constant of SiO heating said plurality of substrates while exposing one or more of the plurality of substrates to an inert atmosphere in said process chamber; generating plasma and molecular fragments of a treating compound with an in-situ plasma generation system coupled to said process chamber, said treating compound comprising a C introducing said treating compound into said process chamber; exposing at least one surface of said dielectric film on said plurality of substrates to said plasma; sealing or partially sealing the exposed surfaces of the dielectric film; and restoring or partially restoring the value of the dielectric constant of the low dielectric constant film by replenishing carbon depleted sites with carbon-containing material in the treating compound.
