A new method to determine the work-function difference and its application to calibrate the boron-segregation coefficient

The authors present a technique to determine the work-function difference from a plot of the threshold voltage (V/sub T/) versus oxide thickness (T/sub ox/) curve. The extraction errors caused by the electrical characteristics of the oxide and the SiO/sub 2//Si interface can be minimized by the V/sub T/-T/sub ox/ technique. The boron segregation coefficient can be calibrated from the slope of the V/sub T/-T/sub ox/ curve. Comparisons between the experimental data and simulation results are made, and good agreement is obtained.<
