Metrology, statistical process control (SPC Cpk > 1.67), inline inspection, and automated wafer-level parametric testing enable maximum power semiconductor yield.

  • Process Engineering & Physics in Static Electrical Wafer Probing: In-situ optical emission spectroscopy, real-time RF match monitoring, and automated high-throughput wafer transfer.
  • Thermal Budget & Junction Profiling: Preserving abrupt source/body junctions and ensuring high-temperature stability during back-end processing.
  • Field Crowding Prevention: Rounding trench corners and tailoring termination guard rings to achieve ideal 1D planar breakdown voltages.
  • Yield Impact: Direct correlation between unit-step uniformity and functional high-voltage power die per wafer (DPW).
