200mm GaN-on-silicon technology and GaN power devices

Introduction

Imec takes today’s gallium nitride-on-silicon (GaN-on-Si) technology to a higher level of maturity and reliability, and explores new concepts for next-generation GaN technology. 

We have been pioneering GaN technology for more than 15 years, evolving 200mm/8-inch wafers to realize GaN-on-Si devices at lower costs while maintaining world-class performance. Our research covers GaN epitaxy as well as device engineering and processing technology. 

Anticipate what will be next by joining our GaN industrial affiliation program and become a member of our partner ecosystem to explore and de-risk next-generation GaN epitaxy, integration and device technologies (substrates, isolations and novel devices) with the possibility of extending the application voltage range of GaN beyond 650V.  

We also provide a dedicated package for technology transfer to shorten your time-to-market, or help you to develop a solution tailored to your needs using our state-of-the-art Au-free CMOS compatible 200mm GaN-on-Si technology platform for 200V and 650V (e-mode) power devices. Our platform is also available for low-volume production.

Our GaN technologies include:

Dispersion-free GaN buffers

Imec develops 200V and 650V GaN buffers on top of 200mm/8-inch substrates and qualifies them on the power device level

State-of-the-art GaN power devices

Imec develops large area, high-performance, large threshold voltage (>2V) e-mode high-electron-mobility transistors (HEMTs) and low-leakage/low-turn-on voltage Schottky diodes.
