Neural Networks for Process Optimization

Neural Networks for Process Optimization is the use of feedforward neural networks to model complex, non-linear relationships between process parameters and quality outcomes — then using the trained model to find optimal process settings through inverse optimization or sensitivity analysis.

How Are Neural Networks Used for Optimization?

• Forward Model: Train a NN on (process parameters → quality metrics) using historical data.
• Inverse Optimization: Use the trained model to find inputs that optimize outputs (gradient-based or genetic algorithm).
• What-If Analysis: Explore the parameter space to understand sensitivities and interactions.
• Constraint Handling: Encode process constraints (equipment limits, safety ranges) in the optimization.

Why It Matters

• Non-Linear: Neural networks capture complex, non-linear interactions that linear models miss.
• Multi-Objective: Can optimize for multiple quality metrics simultaneously (CD, uniformity, defects).
• Large Scale: Scale to hundreds of input parameters common in modern process recipes.

Neural Networks for Process Optimization is using AI to find the sweet spot — training models on process data to discover optimal operating conditions.
