Onsemi has signed an agreement with GlobalFoundries to develop and manufacture advanced gallium nitride (GaN) power products using GF’s 200 mm eMode GaN-on-silicon process.
The move will accelerate onsemi’s roadmap for high performance GaN devices and integrated power stages. This will include high-voltage products that meet demands for:
- Artificial intelligence (AI) data centers
- Electric vehicles
- Renewable energy
- Industrial systems
- Aerospace, defense and security
“By combining our 200mm GaN-on-Si platform and U.S.-based manufacturing with onsemi’s deep system and product expertise, we’re accelerating high-efficiency solutions and building resilient supply chains for data centers, automotive, industrial, aerospace and defense, and other critical markets,” said Mike Hogan, CBO at GlobalFoundries. “With onsemi as a key partner, we will continue to advance GaN semiconductors that meet the evolving demands of AI, electrification and sustainable energy.”
Onsemi said it will pair silicon drivers, controllers and thermally enhanced packages with GF’s 650-volt GaN technology. This will include power supplies and DC-DC converters for AI data centers, onboard chargers and DC-DC converters for EVs, solar microinverters and energy storage.
The company said it will now have a portfolio that includes a full spectrum of GaN technologies for low, medium and high voltage lateral GaN to ultra high-voltage vertical GaN.
Some of the GaN innovations in the process technology include:
- Higher frequency operation
- Bidirectional capability
- Integrated functionality
