Outline of Research at the Start

We are walking the forefront in the world which makes these famous institutions and companies focus on the most advanced technology for future AI and 5G applications. Through this research, we would like to develop a whole branch of techniques for high performance and high reliability SiGe MOSFETs.

Outline of Annual Research Achievements

Ultrathin EOT TiN/Y 2 O 3 /SiGe gate stacks with EOT of 1.05 nm, the low D it of 1.1×10 11 eV -1 cm -2 , and comparable leakage current among other reported Si-cap-free SiGe MOS interfaces has been demonstrated. The improvement of the performance and reduction of S.S. have been found in the Si 0.8 Ge 0.2 /SOI pFinFETs with this gate stack.
