Integration of Germanium-on-Insulator and Silicon MOSFETs on a Silicon Substrate

The monolithic integration of germanium-on-insulator (GeOI) p-MOSFETs with silicon n-MOSFETs on a silicon substrate is demonstrated. The GeOI p-MOSFETs are fabricated on the oxide for silicon device isolation based on the newly developed rapid-melt-growth method. CMOS inverters consisting of the silicon n-MOSFET and GeOI p-MOSFET were obtained, and the measured results show that the processing of high-performance GeOI devices is compatible with bulk-silicon technology
