In-line metrology, statistical process control (SPC Cpk > 1.67), scanning acoustic microscopy, and automated wafer-level testing guarantee high-yield sensor production.

  • Process Engineering & Physics in CMOS ASIC STI Device Isolation: Real-time optical emission spectroscopy, laser interferometer endpoint tracking, and high-vacuum robotic handling.
  • Thermal Budget & Interface Integrity: Protecting underlying CMOS electronics during MEMS structural anneals and wafer bonding cycles.
  • Micro-Cavity Vacuum Preservation: Activating non-evaporable getters to maintain sub-mbar cavity pressures for high-Q gyroscopes.
  • Yield Impact: Direct correlation between unit-step CD uniformity, stiction-free drying, and functional sensor die per wafer (DPW).
