Abstract :
The Hall mobilities and Hall concentrations of channel electrons in boron-implanted NMOSFETs were measured at 77 and 300 K. At both temperatures, the mobilities were found to decrease with increasing implantation dose (1011-1012 cm-2) only for electron concentrations <2×1012 cm-2, the effect being more pronounced at 77 K. It is suggested that the mobility degradation is mainly due to impurity scattering
