Flowable gapfill using solvents

Systems and methods for forming films on the surface of a substrate are described. The systems possess aerosol generators which form droplets from a liquid solution made from a solvent and a deposition precursor. A carrier gas may be flowed through the liquid solution and push the droplets toward a substrate placed in a substrate processing region. The droplets pass into the substrate processing region and chemically react with the substrate to form films. The temperature of the substrate may be maintained below the boiling temperature of the solvent during film formation. The solvent imparts a flowability to the forming film and enable the depositing film to flow along the surface of a patterned substrate during formation prior to solidifying. The flowable film results in bottom-up gapfill inside narrow high-aspect ratio gaps in the patterned substrate.
