Zusammenfassung:The invention provides a gas processing apparatus and a gas processing method. The gas processing apparatus includes: an opposing portion that opposes a mounting portion of a substrate in a vacuum container and includes a plurality of first gas ejection ports; a first diffusion space for the process gas, the first diffusion space being provided above the facing portion so as to communicate with each of the first gas ejection ports; a plurality of second gas ejection ports opened in the vertical direction from the top facing the first diffusion space above the first diffusion space; a second diffusion space for the process gas, the second diffusion space being provided above the top so as to communicate with each of the second gas ejection ports; and a plurality of third gas ejection ports,and a plurality of second diffusion spaces that are formed in a row in the circumferential direction of the first diffusion space and communicate with each of the second diffusion spaces, the seconddiffusion spaces being for
