Abstract:
1. A method of manufacturing a semiconductor device comprising the steps of: forming a gate electrode on a semiconductor substrate via a gate-insulating film; introducing a first impurity into the semiconductor substrate using the gate electrode as a mask; introducing a diffusion-controlling substance into the semiconductor substrate to control a diffusion of the first impurity; forming a side wall-insulating film on each side surface of the gate electrode; introducing a second impurity of the same conductivity type as the first impurity into the semiconductor substrate deeper than an introduced portion of the first impurity using the gate electrode and the side wall-insulating film as masks; activating the first and second impurities by a first annealing treatment; and further activating the first and/or second impurities by a second annealing treatment of an annealing time of not longer than 100 milliseconds.
