Abstract:
A substrate for RF devices includes a polycrystalline ceramic core and an interlayer structure. The interlayer structure includes a first silicon oxide layer coupled to the polycrystalline ceramic core, a polysilicon layer coupled to the first silicon oxide layer, a second silicon oxide layer coupled to the polysilicon layer, a barrier layer coupled to the second silicon oxide layer, a third silicon oxide layer coupled to the barrier layer, and a substantially single crystalline silicon layer coupled to the third silicon oxide layer.

Claim (Index 17):
A method of fabricating a radio frequency (RF) device, the method comprising:\n providing a polycrystalline ceramic core; forming an interlayer structure coupled to the polycrystalline ceramic core, the interlayer structure comprising:\n a first silicon oxide layer coupled to the polycrystalline ceramic core; \n a polysilicon layer coupled to the first silicon oxide layer; \n a second silicon oxide layer coupled to the polysilicon layer; \n a barrier layer coupled to the second silicon oxide layer; \n a third silicon oxide layer coupled to the barrier layer; and \n a substantially single crystalline silicon layer coupled to the third silicon oxide layer; \n growing an epitaxial GaN layer coupled to the substantially single crystalline silicon layer; growing a two-dimensional electron gas (2DEG) inducing layer coupled to the epitaxial GaN layer; and forming a field effect transistor (FET) comprising:\n a drain coupled to a first region of the 2DEG inducing layer; \n a source coupled to a second region of the 2DEG inducing layer; \n a gate dielectric layer coupled to a third region of the 2DEG inducing layer; and \n a gate coupled to the gate dielectric layer.
