Abstract:
1. A method of processing a substrate, the method comprising: generating a first plasma from a first reaction gas; generating a second plasma from a second reaction gas; extracting a first ingredient used for processing the substrate from ingredients in the first plasma; extracting a second ingredient used for processing the substrate from ingredients in the second plasma; and individually applying the first ingredient and the second ingredient to the substrate that is held in a processing chamber, wherein: extracting the first ingredient from the first plasma includes flowing the first plasma through a first extracting hole defined in a shower head, the first extracting hole having a size that allows only the first ingredient from ingredients in the first plasma to pass therethrough, extracting the second ingredient from the second plasma includes flowing the second plasma through a second extracting hole defined in the shower head, the second extracting hole having a size that allows only the second ingredient from ingredients in the second plasma to pass therethrough, individually applying the first ingredient to the substrate includes injecting the first ingredient from the first extracting hole to the substrate that is held in the processing chamber, individually applying the second ingredient to the substrate includes injecting the second ingredient from the second extracting hole to the substrate that is held in the processing chamber.
