Abstract:
Methods and devices integrating circuitry including both III-N (e.g., GaN) transistors and Si-based (e.g., Si or SiGe) transistors. In some monolithic wafer-level integration embodiments, a silicon-on-insulator (SOI) substrate is employed as an epitaxial platform providing a first silicon surface advantageous for seeding an epitaxial III-N semiconductor stack upon which III-N transistors (e.g., III-N HFETs) are formed, and a second silicon surface advantageous for seeding an epitaxial raised silicon upon which Si-based transistors (e.g., Si FETs) are formed. In some heterogeneous wafer-level integration embodiments, an SOI substrate is employed for a layer transfer of silicon suitable for fabricating the Si-based transistors onto another substrate upon which III-N transistors have been formed. In some such embodiments, the silicon layer transfer is stacked upon a planar interlayer dielectric (ILD) disposed over one or more metallization level interconnecting a plurality of III-N HFETs into HFET circuitry.

Claim (Index 31):
The device of  claim 26 , wherein the one or more metallization levels include:\n a first metallization level over first gate electrodes and first source/drain terminals within the first substrate region; a plurality of second metallization levels over second gate electrodes and second source/drain terminals within the second substrate region; and a third metallization level over both the first metallization level and the second metallization levels, the third metallization level interconnecting the first metallization level with at least an uppermost one of the second metallization levels.
