Abstract: In a reverse profiling method, first and second processes produce first and second groups of MOSFETs, respectively. In the first process, channel impurities are implanted into a semiconductor substrate after implantation of source/drain impurities and annealing of the semiconductor substrate. Consequently, the annealing modulates channel impurity density distribution. On the other hand, in the second process, source/drain impurities are implanted into a semiconductor substrate after implantation of channel impurities and annealing of the semiconductor substrate. The annealing does not modulate channel impurity density distribution in the second process. First threshold voltage-gate length characteristics of the MOSFETs of the first group are found. Similarly, second threshold voltage-gate length characteristics of the MOSFETs of the first group are found.
