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.
