Abstract:
Methods of forming a thin-film piezoelectric acoustic filter, a GaN-channel/buffer Bragg reflector, and a monolithically integrated GaN HEMT PA and CMOS over a [111] crystal orientation Si handle of a SOI wafer and resulting devices are provided. Embodiments include providing a SOI wafer including a [111] crystal orientation Si handle, a BOX layer, and a top Si layer; forming a CMOS device over the top Si layer; and forming a Bragg reflector over the [111] crystal orientation Si handle wafer, the Bragg reflector including a GaN stack with alternating layers of high/low acoustic impedance.

Claim (Index 6):
The method according to  claim 1 , comprising forming GaN stack by:\n forming a buffer layer over the [111] crystal orientation Si handle wafer; forming a GaN channel layer over the buffer layer; forming an AlGaN/AlN barrier layer over the GaN channel layer; and forming a silicon nitride (SiN) or silicon dioxide (SiO 2 ) passivation layer over the AlGaN/AlN barrier layer.
