    Abstract: Various reactors for growing thin films on a substrate (16) by subjecting the substrate (16) to alternately repeated surface reactions of vapor-phase reactants are disclosed. In one embodiment, the reactor (12) comprises a reaction chamber (14). A showerhead plate (67) divides the reaction chamber (14) into upper and lower parts. A first precursor is directed towards the lower half of the reaction chamber (14) and a second precursor is directed towards the upper half of the reaction chamber (14). The substrate (16) is disposed within the lower half of the reaction chamber (14). The showerhead plate (67) includes plurality passages (72) such that the upper half is in communication with the lower half of the reaction chamber (14). In another arrangement, the reaction chamber (14) includes a shutter plate (120). In other arrangements, the showerhead plate (67) is arranged to modify the local flow patterns of the gases flowing through the reaction chamber (14).
