Claim 15:
16. A method for forming a dielectric material, comprising:
filling, from a bottom upwards, an opening having an aspect ratio greater than 5 on a substrate with a dielectric material with a first density formed from sequentially applying a first remote plasma in a continuous power mode to deposit the dielectric material in the opening during a first duration, a first bias plasma in a continuous power mode to increase a density of the dielectric material to a second density greater than the first density in the opening during a single, continuous first treatment during a second duration, and a second remote plasma in combination with a second bias plasma to an interior processing region of a processing chamber where the substrate is disposed in a single, continuous second treatment that is different from the single, continuous first treatment for a third duration, wherein the second remote plasma and the second bias plasma are continuously generated by continuous RF power that operates in a continuous power mode for an entire duration of the third duration of the single, continuous second treatment; and
increasing a hydrophobicity of the dielectric material by a water contact angle of at least 10 degrees after the single, continuous second treatment is performed, wherein a dielectric constant of the dielectric material is maintained after the single, continuous second treatment.
