Abstract:
1. A substrate processing apparatus comprising: a process container accommodating a substrate; a first process gas supply unit configured to supply a first process gas to a center portion of the substrate from above the substrate; a first reactive gas supply unit configured to supply a first reactive gas to the center portion of the substrate from above the substrate; a second process gas supply unit configured to supply a second process gas to the center portion of the substrate from a lateral direction with respect to the substrate; a second reactive gas supply unit configured to supply a second reactive gas to the center portion of the substrate from the lateral direction with respect to the substrate; an activation unit configured to activate at least one of the first reactive gas and the second reactive gas to generate plasma; a plasma adjusting electrode installed above the center portion of the substrate outside the process container, wherein the plasma adjusting electrode is configured to adjust densities of the plasmas at the center portion and at a peripheral portion of the substrate and control the plasma adjusting electrode to move upward and downward; and a control unit configured to control the first process gas supply unit, the second process gas supply unit, the first reactive gas supply unit, the second reactive gas supply unit, the activation unit, and the plasma adjusting electrode.
