Virtual Fab

A synthetic data infrastructure for AI training Solves data scarcity and missing edge-case coverage with domain knowledge-based synthetic generation.

What it does

  • 01

    Validated synthetic data generation

    Generate synthetic wafer data grounded in process, equipment and defect rules, then cross-validate against real fab measurements to confirm distribution alignment.
