  • Publication number: 20140118751
    Abstract: A method of processing a substrate according to a PECVD process is described. Temperature profile of the substrate is adjusted to change deposition rate profile across the substrate. Plasma density profile is adjusted to change deposition rate profile across the substrate. Chamber surfaces exposed to the plasma are heated to improve plasma density uniformity and reduce formation of low quality deposits on chamber surfaces. In situ metrology may be used to monitor progress of a deposition process and trigger control actions involving substrate temperature profile, plasma density profile, pressure, temperature, and flow of reactants.

  • Patent number: 8587321
    Abstract: A system and method for the detection of plasma excursions, such as arcs, micro-arcs, or other plasma instability, during plasma processing by directly monitoring RF current just prior to reaching an RF power electrode of a plasma processing chamber is provided. The monitored RF current may be converted to an RF voltage and then passed through a succession of analog filters and amplifiers to provide a plasma excursion signal. The plasma excursion signal is compared to a preset value, and at points where the plasma excursion signal exceeds the preset value, an alarm signal is generated. The alarm signal is then fed back into a system controller so that an operator can be alerted and/or the processing system can be shut down. In one embodiment, the RF current amplified and converted to a digital signal for digital filtering and processing. In certain embodiments, multiple processing regions can be monitored by a single detection control unit.

  • Patent number: 8502689
    Abstract: The present invention provides a system and method for the detection of plasma excursions, such as arcs, micro-arcs, or other plasma instability, during plasma processing by directly monitoring direct current (DC) bias voltage on an RF power electrode of a plasma processing chamber. The monitored DC bias voltage is then passed through a succession of analog filters and amplifiers to provide a plasma excursion signal. The plasma excursion signal is compared to a preset value, and at points where the plasma excursion signal exceeds the preset value, an alarm signal is generated. The alarm signal is then fed back into a system controller so that an operator can be alerted and/or the processing system can be shut down. In certain embodiments, multiple processing regions can be monitored by a single detection control unit.
