Claim 0:
1. A method for fabricating a GaN chip, comprising:
growing a Nb2N sacrificial layer on an original substrate, and growing a GaN insertion layer on the Nb2N sacrificial layer;
growing a Ta2N sacrificial layer on the GaN insertion layer, and growing a semiconductor layer on the Ta2N sacrificial layer to form a GaN wafer;
bonding the GaN wafer with a first surface of a temporary carrier, and removing the Nb2N sacrificial layer and the Ta2N sacrificial layer; and
transferring remaining material after removal of the Nb2N sacrificial layer and the Ta2N sacrificial layer to a target substrate, and removing the temporary carrier from the remaining material to form the GaN chip.
