GlobalWafers America

MEMC, a GlobalWafers subsidiary, is developing a facility to manufacture 300mm silicon-on-insulator wafers in St. Peters, Missouri. NIST identifies approximately 130 manufacturing jobs for this project. The announced $4 billion investment covers facilities in Texas and Missouri; a separate St. Peters investment amount has not been established.

Why this project qualifies

With 130 permanent operating jobs announced, this project clears AFT's 100-permanent-job threshold (AFT includes any project meeting $100 million in facility-specific investment OR 100 permanent operating jobs). This project also meets AFT's primary-source verification and physical U.S. manufacturing-footprint requirements.

Why it matters

The semiconductors context.

Semiconductor fabrication plants, known as fabs, rank among the most capital-intensive industrial facilities ever built—often requiring $10–$30 billion and several years from groundbreaking to initial production. The CHIPS and Science Act of 2022 accelerated a U.S. construction cycle spanning advanced chip fabrication, legacy-node production, semiconductor equipment, packaging, and critical materials. These projects create long-term manufacturing footprints while attracting suppliers, infrastructure investment, and specialized technical work.
