Abstract:
1. A method for forming a thin film using radicals generated by plasma, comprising: making a first relative movement between a substrate and a deposition reactor in a direction parallel to a surface of the substrate for depositing the thin film; injecting a reactant precursor into a gap between a first electrode and a second electrode of the deposition reactor; generating radicals of the reactant precursor using plasma at the deposition reactor; injecting the source precursor into a region and another region within the deposition reactor via a channel formed in the first electrode; mixing the radicals with a source precursor in the region within the deposition reactor into first mixture; forming a first thin film on a portion of the surface of the substrate by exposing the portion of the surface of the substrate to the first mixture after making the first relative movement; making a second relative movement between the substrate and the deposition reactor in the direction parallel to the surface of the substrate; exposing the portion of the surface of the substrate to the source precursor that is not mixed with the radicals after making the second relative movement; making a third relative movement between the substrate and the deposition reactor in the direction parallel to the surface of the substrate; mixing the radicals with the source precursor in the other region within the deposition reactor into second mixture; and forming a second thin film on the first film by exposing the first film to the second mixture after making the third relative movement.
