- Abstract
- We propose a novel power metal oxide semiconductor field effect transistor (MOSFET) employing a strained-Si channel structure to improve the current drivability and on-resistance characteristic of the high-voltage MOSFET. A 20 nm thick strained-Si law field channel NMOSFET with a 0.75 fan thick Si 0.8Ge0.2 buffer layer improved the drive current by 20% with a 25% reduction in on-resistance compared with a conventional Si channel high-voltage NMOSFET, while suppressing the breakdown voltage and subthreshold slope characteristic degradation by 6% and 8% respectively. Also, the strained-Si high-voltage NMOSFET improved the transconductance by 28% and 52% at the linear and saturation regimes.
