Abstract:
1. A process for depositing a thin film material on a substrate, comprising simultaneously directing a series of gas flows from the output face of a delivery head of a thin film deposition system toward a surface of a substrate, and wherein the series of gas flows comprises at least a first reactive gaseous material, an inert purge gas, and a second reactive gaseous material, wherein the first reactive gaseous material is capable of reacting with a substrate surface treated with the second reactive gaseous material, wherein the delivery head comprises: (a) at least a first, a second, and a third inlet port for receiving the first reactive gaseous material, the second reactive gaseous material, and the inert purge gas, respectively; (b) an output face in proximity to the surface of the substrate comprising a plurality of elongated output openings, wherein each of the inlet ports is independently connected, respectively, to at least one first, second, and third elongated output opening for supplying the respective gaseous materials to the substrate; and (c) a network of interconnecting supply chambers and directing channels for routing each of the first, the second, and the third gaseous materials from its corresponding inlet port to its corresponding elongated output opening; and wherein at least one gas diffusing channel, formed by two adjacent plates in which at least one of the two adjacent plates has a relief pattern in the area of the gas diffusing channel, is connected to only a given one of the elongated output openings.
