Abstract :
Various advanced germanium (Ge) metal-oxide-semiconductor field-effect transistor (MOSFET) technologies with high-permittivity (high-κ) gate dielectrics and shallow junctions have been demonstrated. Numerous novel Ge technologies on surface cleaning, gate dielectric, and dopant incorporation are presented In addition, we disclose an innovative self-aligned gate-last fabrication process not only to demonstrate functional Ge MOSFETs, but also to provide a vehicle to characterize many novel material integration schemes.
