  • Patent number: 9881804
    Abstract: This disclosure relates to a plasma processing system and methods for high precision etching of microelectronic substrates. The system may include a plasma chamber that may generate plasma to remove monolayer(s) of the substrate. The plasma process may include a two-step process that uses a first plasma to form a thin adsorption layer on the surface of the microelectronic substrate. The adsorbed layer may be removed when the system transitions to a second plasma or moves the substrate to a different location within the first plasma that has a higher ion energy. In one specific embodiment, the transition between the first and second plasma may be enabled by changing the position of the substrate relative to the source electrode with no or relatively small changes in plasma process conditions.

  • Patent number: 9852893
    Abstract: A method and apparatus is provided for obtaining a low average electron energy flux onto a substrate in a processing chamber. A processing chamber includes a substrate support therein for chemical processing. An energy source induced plasma, and ion propelling means, directs energetic plasma electrons toward the substrate support. A dipole ring magnet field is applied perpendicular to the direction of ion travel, to effectively prevent electrons above an acceptable maximum energy level from reaching the substrate holder. Rotation of the dipole magnetic field reduces electron non-uniformities.
