The GaN crystal quality of this new GaN-on-Sapphire substrate and the GaN substrate are at a comparable level.

Currently, PQGaN is a high-quality single-layer GaN material that can be used as a substrate. Customers can extend the GaN structure on top of it.

Furthermore, we can also manufacture customer-specified GaN extension structures on PQGaN substrates on your behalf if needed.
