Bulk Gallium Nitride

High voltage and high frequency power electronic devices created with Bulk GaN have fewer impurities thus improving performance over Gallium Nitride grown a substrate including

  • Silicon (Si)
  • Sapphire (Al2O3)
  • Silicon Carbide (Si)

Few companies can grow Bulk, or Free Standing, Gallium Nitride.

But UniversityWafer, Inc. and our partners can!


Below are just some of our Free Standing and Bulk 100mm GaN substrates

Bulk Gallium Nitride (GaN) and GaN Wafers

We have a large selection of Bulk GaN wafers in stock.

Our Bulk GaN including N-type and Semi insulating type from 2" to 4", as well as small pieces of customized dimensions,also different of crystal orientations,pls see attachment for our general wafer spec.

Besides Bulk GaN wafer, we also do well on GaN-on-Silicon/SiC/Sapphire Based HEMT wafer,of which very popular GaN wafer in recently years,vand will come being main stream on Power and RF applications.

Please let us know if you have an interest.
