GaN/Si Epiwafers-GaN Substrate

Q: How are GaN wafers made?

It is made with original HVPE method and wafer processing technology , which has been originally developed for many years. The features are high crystalline, good uniformity, and superior surface quality. GaN substrates are used for LD applications (violet, blue and green).

GaN-on-Si wafers have grown in popularity in the production of High Electron Mobility Transistors (HEMT). It and related binaries InN and AlN, as well as ternary compounds.

Will Gallium Nitride Replace Silicon Wafers?

Maybe in the future ,but Silicon wafers also have unique uses.

Is GaN better than silicon?

Power density is greatly improved in gallium nitride devices compared to silicon ones because GaN has the capacity to sustain much higher switching frequencies. It also has an increased ability to sustain elevated temperatures
