    摘要: In order to obtain a semiconductor device having an internal wire of low resistance, a conductive layer whose surface is silicified is provided in a surface of a semiconductor substrate. A conductor whose surface is silicified is provided on the semiconductor substrate in proximity to the conductive layer. This semiconductor device is provided with an internal wiring layer, which is formed by a titanium film and a titanium silicide layer for electrically connecting the surface of the conductive layer and a surface of an end of the conductor with each other, to cover a side wall surface and a bottom surface of a contact hole.

    摘要: 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 .ANG. from the surface of silicon substrate. Thereby, a transistor structure which can be easily miniaturized can be obtained.

    摘要: Each memory cell of a dynamic random access memory comprises a semiconductor layer of a first conductivity type, one and the other impurity regions of a second conductivity type, a gate electrode, a capacitor impurity region of the first conductivity type, and a capacitor electrode. The semiconductor layer of the first conductivity type comprises a first surface and a second surface located opposite to the first surface. One and the other impurity regions are formed spaced apart from each other in the semiconductor layer so as to define a channel region with a channel surface being a part of the first surface of the semiconductor layer. The gate electrode is formed on the channel surface through a gate insulating film. The capacitor impurity region is formed opposing to the channel region, near the second surface of the semiconductor layer and having a concentration higher than that of the semiconductor layer. The capacitor electrode is formed on the capacitor impurity region through a dielectric film. Reduced surface area occupied by each memory cell comprising a field effect transistor and a capacitor enables miniaturization of the memory cell. Electric charges generated by the impact ionization phenomenon are stored in the capacitor, so that a power consumed in a writing operation of data can be reduced.
