Abstract
A boron diffusion region is formed at a surface of a silicon substrate. A pair of n-type source/drain regions are formed at a surface of boron diffusion region. A gate electrode is formed at a region located between paired source/drain regions with a gate insulating film therebetween. A nitrogen implanted region is formed at the surface of silicon substrate located between paired n-type source/drain regions. Nitrogen implanted region has a peak nitrogen concentration at a position of a depth not exceeding 500 Å from the surface of silicon substrate. Thereby, a transistor structure which can be easily miniaturized can be obtained.
