Advanced Process Control Solutions for Improved Yield, OEE & Process Stability
Advanced Process Control (APC) plays a critical role in semiconductor and advanced electronics manufacturing by enabling precise process optimization, improved yield, and enhanced equipment performance. Successful implementation of an advanced process control system requires a thorough understanding of fab and assembly environments combined with innovative automation technologies.
Over the years, eInnoSys has successfully implemented multiple advanced process control solutions across various semiconductor factories and assembly facilities, helping manufacturers achieve measurable improvements across critical performance benchmarks:
- Measurable Yield Improvement: Reducing defect density and wafer scrap through early variations drift tracking.
- Optimized Cycle Time: Streamlining recipe execution and reducing process idle overheads.
- Enhanced Overall Equipment Effectiveness (OEE): Maximizing tool performance, throughput, and equipment uptime.
Solutions Overview
eInnoSys delivers high-performance advanced process control software designed to monitor, analyze, and optimize manufacturing processes in real time. Our APC solutions integrate data analytics, automation, and predictive modeling to improve process stability and production efficiency.
Run-to-Run (R2R) Control and Wafer-to-Wafer (W2W) Control
eInnoSys provides advanced Run-to-Run and Wafer-to-Wafer control solutions that analyze process data and take appropriate corrective actions during wafer unload and load operations. The system can automatically implement stop feeding when necessary to prevent defects and improve manufacturing consistency.
Feedback Control Systems
Feeding Overlay Measurement into Steppers
By feeding overlay metrology measurements directly into stepper equipment, eInnoSys APC solutions significantly improve alignment accuracy, resulting in:
- Improved Yield
- Better Process Stability
- Reduced Cycle Time
- Improved OEE Performance
Feeding Metrology Results into Process Equipment
This integration enables automated process corrections and ensures consistent production quality. eInnoSys APC solutions seamlessly integrate metrology data directly into critical process steps, including:
- Grinders
- Polishers
APC vs. FDC vs. SPC: Key Differences
*Note: APC handles the “adjustment,” FDC handles the “tool health,” and SPC handles the “long-term quality trend.”
