GaN Epiwafers and applications
GaN epitaxial wafers
GLC semiconductor provides the most advanced GaN epitaxial layers deposited on 6 inch Si-wafers for 650V power and RF, Sensors applications.
Gallium Nitride (GaN) materials are needed to reach the next levels of performance in power and RF electronics, not possible with Silicon semiconductors.
GaN based High Electron Mobility Transistor (HEMT) devices have high electron mobility and a wide band gap energy that makes them ideally suited for fast switching and high voltage operation under high temperature conditions. Furthermore, GaN has ten times the breakdown voltage of silicon, so it is naturally suited to high voltage operation required in power applications.
- The most significant advantages of GaN devices are:
- Lower ON-resistance
- Higher breakdown voltages
- Higher operating temperatures
- Higher switching frequencies
- Low RF losses
