  • Publication number: 20110097491
    Abstract: A fluid conveyance system for thin film material deposition includes a first fluid distribution manifold and a second distribution manifold. The first fluid distribution manifold includes an output face that includes a plurality of elongated slots. The plurality of elongated slots includes a source slot and an exhaust slot. The second fluid distribution manifold includes an output face that includes a plurality of openings. The plurality of openings include a source opening and an exhaust opening. The second fluid distribution manifold is positioned spaced apart from and opposite the first fluid distribution manifold such that the source opening of the output face of the second fluid distribution manifold mirrors the source slot of the output face of the first fluid distribution manifold and the exhaust opening of the output face of the second fluid distribution manifold mirrors the exhaust slot of the output face of the first fluid distribution manifold.
