Abstract:
1. A fabricating method of nitride semiconductor substrate, comprising: providing a first substrate, the first substrate comprising a first base material, a nitride semiconductor template layer stacked on the first base material, and a first dielectric layer stacked on the nitride semiconductor template layer; patterning the first dielectric layer and the nitride semiconductor template layer; providing a second substrate, the second substrate comprising a second base material and a second dielectric layer stacked on the second base material; transferring the nitride semiconductor template layer and the first dielectric layer of the first substrate onto the second dielectric layer of the second substrate through bonding and transferring processes; growing a nitride semiconductor thick film from the nitride semiconductor template layer through an epitaxy process; and separating the nitride semiconductor thick film and the second substrate.
