Abstract :
The influence of high substrate doping on the characteristics of small-geometry n- and p-MOSFETs down to 0.1 /spl mu/m has been investigated in detail. A practical limiting impurity concentration is found to exist at around 2/spl sim/5/spl times/10/sup 18/ cm/sup -3/ depending upon the application. In addition, unusual behaviors are found in the hot carrier characteristics in the region of high doping concentration.<>
