Wolfspeed’s $5 Billion Silicon Carbide Fab Nears Completion

New Wolfspeed SiC Manufacturing Facility to Begin Production in June 2025

Wolfspeed’s ambitious $5 billion silicon carbide (SiC) wafer fabrication plant is now nearing completion. According to recent reports, Wolfspeed expects to fully take over the facility by March 2025 and officially begin 8-inch (200mm) SiC wafer production in June 2025.

The new facility is located in Chatham County, North Carolina, and is set to become the world’s largest silicon carbide fab. Wolfspeed first announced the project in September 2022, with the construction reaching its topping-out milestone in March 2024.

Strengthening Wolfspeed’s Leadership in Silicon Carbide

As a global leader in SiC technology, Wolfspeed has significant expertise in substrate development, epitaxy growth, and device manufacturing. The Chatham County SiC fab is expected to substantially expand Wolfspeed’s SiC production capacity, helping to meet the growing demand for next-generation semiconductors that are critical for energy transition and AI-driven applications.

Key Highlights of the Chatham County SiC Fab:

World’s Largest SiC Fab – Set to dominate the global SiC market once fully operational.
$5 Billion Investment – One of the most expensive SiC manufacturing projects in history.
8-inch SiC Wafers – Increasing efficiency and reducing costs in EVs, AI chips, and power electronics.
Supports AI and Green Energy – Critical for AI servers, renewable energy, and high-efficiency power systems.

Government Support & CHIPS Act Funding

The U.S. federal, state, and local governments have pledged over $700 million in financial support for the project, with part of the funding already allocated for site preparation.

Meanwhile, Wolfspeed is actively working in Washington to secure additional funding through the U.S. CHIPS Act, which aims to boost domestic semiconductor manufacturing and reduce reliance on foreign supply chains.

With the Chatham County fab set to go live by mid-2025, Wolfspeed is positioning itself at the forefront of the global silicon carbide revolution, accelerating the transition toward energy-efficient, high-performance semiconductor technologies.
