Abstract
A film deposition apparatus includes a body formed with openings and cavity, a spray assembly, and a gas assembly. The spray assembly sprays a precursor stream into the cavity for forming a film on a substrate. The gas assembly injects one or more gases into the cavity through the openings to shape the precursor stream and improve directionality and utilization of the precursor stream. The film deposition apparatus can operate with one or more plasma generators to form a laminated film on the substrate. The laminated film may have three layers of film: a first film formed through reaction of a first precursor with plasma, a second film being a composite of the first precursor and a second precursor, and a third film formed through sonification of the second precursor on top of the second film. The second precursor can infiltrate into the first film and fill defects therein.
