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 19):
A device comprising:\n a silicon on insulator (SOI) wafer, the SOI wafer comprising a [111] crystal orientation silicon (Si) handle wafer, a buried oxide (BOX) layer, and a top Si layer; a complimentary metal-oxide-semiconductor (CMOS) device over the top Si; a gallium nitride (GaN) stack over the [111] crystal orientation Si handle; a GaN high-electron-mobility transistor power amplifier (GaN HEMT PA) in and over the GaN stack; a thin-film Lamb acoustic wave filter over the GaN stack; a via through the first Mo or W layer on opposite sides of the thin-film Lamb acoustic wave filter; and a cavity under the thin-film Lamb acoustic filter in a passivation layer of the GaN stack.
