| 摘要 |
Various reactors for growing thin films on a substrate by subjecting the substrate to alternately repeated surface reactions of vapor-phase reactants are disclosed. The reactor according to the present invention includes a reaction chamber, a substrate holder, a showerhead plate, a first reactant source, a remote radical generator, a second reactant source, and an exhaust outlet. The showerhead plate is configured to define a reaction space between the showerhead plate and the substrate holder. The showerhead plate includes a plurality of passages leading into the reaction space. The substrate is disposed within the reaction space. A first non-radical reactant is supplied through the showerhead plate to the reaction space. The remote radical generator produces the radicals of a second reactant supplied from the second reactant source. The radicals are supplied directly to the reaction space without passing through the showerhead plate.
