Efficient power conversion – lower power losses

High Voltage Power

EpiGaN provides state-of-the-art GaN epitaxial layers deposited on 4, 6 inch and 200 mm Si-wafers for 650V power applications.

Our typical epi structure includes:

  • SiN passivation: Deposited in-situ, SiN gives unparalleled dynamic behavior, enhanced material stability and device reliability
  • Heterostructures: AlGaN barrier. Other barriers like AlN and InAlN are possible as well. 
  • Active GaN channel: High mobility and low sheet resistivity
  • HV Buffer: Low leakage, high breakdown voltage, no dispersion and low bow
  • Substrate: High quality conductive Silicon (111)

Besides an in-Situ SiN cap layer, we can also grow GaN cap layers.
