Patent number: 10332727Abstract: A plasma processing method is provided. The method includes receiving a substrate in a substrate support that is configured to be movable along a linear path. The method includes providing at least one process gas into a plasma microchamber. The plasma microchamber is disposed in a processing head having a length that is at least longer than a diameter of the substrate, and said length is perpendicular to said linear path. The method includes generating a plasma in the plasma microchamber by applying power to the plasma microchamber and applying a bias power to the substrate support.
