    摘要: In a plasma processing chamber, a method for processing a substrate is provided. The method includes supporting the substrate in the plasma processing chamber configured with an upper electrode (UE) and a lower electrode (LE), configuring at least one radio frequency power source to ignite plasma between the UE and the LE, and providing a conductive coupling ring, the conductive coupling ring is coupled to the LE to provide a conductive path. The method further includes providing a plasma-facing-substrate-periphery (PFSP) ring, the PFSP ring being disposed above the conductive coupling ring. The method yet further includes coupling the PFSP ring to at least one of a direct current (DC) ground through an RF filter, the DC ground through the RF filter and a variable resistor, a positive DC power source through the RF filter, and a negative DC power source through the RF filter to control plasma processing parameters.

    摘要: In order to provide a high impedance between two sensor terminals, for instance for connecting a Rogowski transducer to a circuit breaker, but to prevent the coupling-in of interference signals in the case of a non-connection to the terminals, two auxiliary terminals are connected. In at least one embodiment, they are connected in such a manner that in the basic state, the sensor terminals are short circuited but in the case of a connection, for example of a plug to the sensor terminals and simultaneously to the auxiliary terminals, the short circuit is canceled with external short circuiting of the auxiliary terminals.

    摘要: A method of detecting substrate arcing in a semiconductor plasma processing apparatus is provided. A substrate is placed on a substrate support in a reaction chamber of a plasma processing apparatus. Process gas is introduced into the reaction chamber. A plasma is generated from the process gas and the substrate is processed with the plasma. Intensities of real-time spectrometry signals of selected gas species produced in the reaction chamber during plasma processing are monitored. The selected gas species are generated by a substrate arcing event. The arcing event is detected when the intensities are above a threshold value.
