Self-Aligned Via (SAV) Integration to Eliminate Overlay Shorts

Advanced process integration ensures tight sub-nanometer critical dimension tolerances, zero-defect contamination margins, and optimal battery lifetime.

Metrology, statistical process control (SPC Cpk > 1.67), inline inspection, and physical compact models enable high-volume manufacturing yield across 200mm/300mm IoT wafers.

  • Self-Aligned Via (SAV) Integration to Eliminate Overlay Shorts: Rigorous in-situ optical emission spectroscopy and automated fab sensor telemetry.
  • Ultra-Low Leakage Optimization: Balancing on-state saturation current against sub-pA/cell off-state standby leakage.
  • Thermal Budget Management: Preventing dopant deactivation and silicide agglomeration across heterogeneous modules.
  • Yield Impact: Direct correlation between unit step CD uniformity and total good functional die per wafer (DPW).
