Spartan™: 20 kW Unipolar Pulse Generator

Application: Wafer Bias


  • Matching network not required – reduces complexity
  • Improved ion energy distribution control leads to improved etch quality
  • Fast pulse rise time optimizes wafer on-time (time wafer spends at nonzero voltages)
  • Retrofit older processing tools to upgrade capabilities
