A study was conducted on the strained Si and SiGe metal-oxide field-effect transistors (MOSFET), fabricated using a thermal budget. It was found that the Ge content in the SiGe virtual substrate varied from 10% to 30%. High levels of strain reduced the critical thickness of strained Si above which Si became unstable and susceptible to relaxation during high-temperature device fabrication. The results identified the appropriate parameter window for virtual substrate Ge composition if acceptable MOSFET on-state performance, off-state performance, device yield and reliability were to be achieved using a thermal budget process.
