For scaled metal-oxide semiconductor field effect transistor (MOSFET) devices, normal operation is seriously affected by the static gate tunneling leakage current due to the ultra-thin gate oxide of MOSFET, and the novel MOSFET devices based on strained Si are similar to bulk Si devices in the effects. To illustrate the impact of gate leakage current on performance of novel strained Si device, a theoretical gate tunneling current predicting model by integral approach following the analysis of quasi-two-dimensional surface potential is presented in this study. On the basis of theoretical model, performance of MOSFET device was quantitatively studied in detail using ISE simulator, including different gate voltages and gate oxide thickness. The experiments show that simulation results agree well with theoretical analysis, and the theory and experimental data will contribute to future VLSI circuit design.
