Virtual Fab is a comprehensive simulation environment that models the entire semiconductor manufacturing flow — from wafer start to finished product, including process steps, equipment behavior, lot scheduling, and yield, enabling factory-level optimization without physical experiments.

Virtual Fab Capabilities

• Process Simulation: Model each unit process (lithography, etch, deposition) with physical or empirical models.
• Factory Simulation: Discrete-event simulation of lot flow, queuing, tool utilization, and cycle time.
• Yield Modeling: Statistical yield models based on defect density, parametric distributions, and process windows.
• Cost Modeling: Calculate cost-per-wafer incorporating tools, materials, labor, and overhead.

Why It Matters

• New Process Introduction: Simulate a new process flow before committing silicon.
• Bottleneck Analysis: Identify capacity bottlenecks and optimize tool investment.
• Training: Train new engineers on virtual fab operations without production risk.

Virtual Fab is the semiconductor flight simulator — modeling the entire factory for optimization, training, and planning without risking real production.
