Bulk GaN substrate
1. What is GaN substratesGallium Nitride is one kind of wide-gap compound semiconductors. It is made with original HVPE method and wafer processing technology, which has been originally developed for many years.
2.Application
Laser diodes for Blu-ray Disc™ players and light projectors
Future application: GaN PN-diode with high breakdown voltage over 3,000V and low on-resistance of 1mΩ·cm2
long-lived, efficient and reliable optoelectronic and electronic devices
high brightness LEDs for general lighting and high power, high frequency transistors for cellular phone base stations and defence applications.
