Dow Corning Joins The Imec GaN Affiliation Program

The firms will work together to bring GaN epi-technology on silicon wafers to a manufacturing scale.

Dow Corning has formalized an agreement to enter the imec multi-partner industrial R&D program on GaN semiconductor materials and device technologies.

The program focuses on the development of the next generation GaN power devices and LEDs. The collaboration between Dow Corning and imec will concentrate on bringing the GaN epi-technology on silicon wafers to a manufacturing scale.

Due to the combination of superior electron mobility, higher breakdown voltage and good thermal conductivity properties, GaN/AIGaN heterostructures offer a high switching efficiency for the next generation power and RF devices compared to the current devices based on silicon. A process for high quality GaN epi-layers on Si substrates is key in obtaining superior power & RF devices.

 



Accurate control of the epi-growth process to master substrate bow, epi-layer defectivity and uniformity while maintaining high epi-reactor throughput are needed to reduce the overall technology cost. Imec has pioneered GaN epi-growth on sapphire, SiC and silicon substrates from 2 to 6 inch substrate sizes and currently focuses on developing GaN epi-layers on 8 inch silicon substrates.

Leveraging the economics of scale and compatibility with high throughput and high capacity 8 inch silicon wafer based process technology will further reduce the cost of GaN devices and LEDs.

As a leading producer of SiC wafers and epitaxy, Dow Corning is leveraging its capability in electronic materials technology and quality supply to bring next generation materials technology to global device manufacturers.

 "By joining the imec GaN Affiliation Program, Dow Corning will rapidly expand its substrate

product portfolio with high quality and affordable GaN epi-wafers for power, RF and LED markets" says Tom Zoes, Global Director, Dow Corning Compound Semiconductor Solutions.

"We are delighted to welcome Dow Corning as a partner in our GaN Affiliation Program. Teaming up with imec's epitaxy and device researchers within our multi-partner environment creates a strong momentum to bring this technology to market," says Rudi Cartuyvels, VP Process Technology at imec.
