Abstract:
1. An apparatus for growing thin films onto a surface of a substrate by exposing the substrate to alternatively repeated surface reactions of vapor-phase reactants, the apparatus comprising: a first reactant source; an inactive gas source; a reaction chamber that provides a space for a first reactant from the first reactant source to react with the surface of the substrate; a first conduit that connects the first reactant source to the reaction chamber; a second conduit that connects the first conduit to the inactive gas source at a first connection point; a third conduit that connects the first conduit to an outlet at a second connection point; a hot zone in which the reaction chamber and the first conduit are positioned; a control valve for controlling the flow of the first reactant into the first conduit, the control valve being positioned outside the hot zone; a second reactant source; a fourth conduit that connects the second reactant source to the reaction chamber; a fifth conduit that connects the inactive gas source to the fourth conduit at a third connection point; and a sixth conduit that is connected to the fourth conduit and the outlet.
