| Summary: | In this paper, we propose a fabrication process of Strained Silicon MOSFET incorporating Dielectric Pocket (SDP-MOSFET). By employing TCAD tools, a systematic process simulation in realizing the SDP-MOSFET structure is done
successfully. By using vertical and horizontal doping profiles, 120 nm gate length with 12 nm gate oxide of the device is observed respectively. The combination of a Silicon Germanium (SiGe) layer and incorporation of dielectric pocket (DP) shows an improved in suppression of short channel effects (SCE) and allows the threshold voltage and the performance of the devices to be optimized. A low leakage current (IOFF), good drive current (ION), higher mobility and lower power consumption are obtained in SDP-MOSFET. Consequently, the threshold voltage (VT) is decreased accordingly in SDP-MOSFET devices and shows a better control of VT roll-off. |
