    摘要: A time-of-flight ion sensor for monitoring ion species in a plasma includes a housing. A drift tube is positioned in the housing. An extractor electrode is positioned in the housing at a first end of the drift tube so as to attract ions from the plasma. A plurality of electrodes is positioned at a first end of the drift tube proximate to the extractor electrode. The plurality of electrodes is biased so as to cause at least a portion of the attracted ions to enter the drift tube and to drift towards a second end of the drift tube. An ion detector is positioned proximate to the second end of the drift tube. The ion detector detects arrival times associated with the at least the portion of the attracted ions.

    摘要: The present invention provides plasma processing systems and methods for providing a set-point temperature for substrates during plasma processing by controlling clamping force or RF power. The plasma processing system includes a plasma chamber, a controller, and an electrostatic power supply. The plasma chamber is arranged to receive an RF power and a source gas for producing plasma. The plasma chamber includes an electrostatic chuck for clamping a substrate in place during plasma processing. The electrostatic chuck includes an electrode and a sensor, which is arranged to monitor temperature of the substrate being processed. The controller is coupled to the sensor to receive the substrate temperature and is configured to generate a control signal for driving the substrate temperature to the set-point temperature. The electrostatic power supply is coupled between the controller and the electrode in the electrostatic chuck. The electrostatic power supply receives the control signal from the controller and generates a voltage adapted to clamp the substrate with a clamping force. In this configuration, the electrostatic power supply provides the voltage to the electrode to clamp the substrate such that the substrate temperature is driven to the set-point temperature.

    摘要: A technique for conformal processing of a substrate having a non-planar surface is disclosed. The technique includes several stages. In a first stage, some surfaces of the substrate are effectively processed. During a second stage, these surfaces are treated to limit or eliminate further processing of these surfaces. During a third stage, other surfaces of the substrate are processed. In some applications, the surfaces that are perpendicular, or substantially perpendicular to the flow of particles are processed in the first and second stages, while other surfaces are processed in the third stage. In some embodiments, the second stage includes the deposition of a film on the substrate.
