We demonstrate monolithic 3D (M3D) integration of vertically stacked CMOS inverters using n-type IGZO and p-type Te TFTs. Vacuum-based fabrication ensures high-quality films, while the stacked architecture shortens interconnects and increases integration density. Compared with planar CMOS, the inverters show robust operation with a simpler process.
