  • Patent number: 7732880
    Abstract: A conventional semiconductor device, for example, a MOS transistor including an offset gate structure has a problem that it is difficult to reduce the device size. In a semiconductor device according to the present invention, for example, in a P-channel MOS transistor including an offset gate structure, a LOCOS oxide film is formed between a source region and a drain region in an N type epitaxial layer. A gate electrode is formed to be positioned on the LOCOS oxide layer. In addition, a P type diffusion layer as the drain region and a P type diffusion layer as the source region are formed with a high positional accuracy with respect to the gate electrode. This structure makes it possible to reduce the device size of the MOS transistor.

  • Patent number: 7547950
    Abstract: A conventional semiconductor device has a problem that it is difficult to obtain a desired breakdown voltage characteristic due to a reduction in a punch-through breakdown voltage between drain and source regions. In a semiconductor device according to the present invention, a P type diffusion layer is formed in an N type epitaxial layer. An N type diffusion layer as a back gate region is formed in the P type diffusion layer. The N type diffusion layer is formed by self-alignment using a drain electrode. This structure makes it possible to increase an impurity concentration of the N type diffusion layer in a vicinity of a P type diffusion layer as a source region. As a result, it is possible to improve a punch-through breakdown voltage between the drain and the source regions, and to achieve a desired breakdown voltage characteristic of the MOS transistor.

  • Publication number: 20080001185
    Abstract: In a semiconductor device, for example, a MOS transistor, of the present invention, a P type diffusion layer as a back gate region is formed in an N type epitaxial layer. An N type diffusion layer as a source region is formed in the P type diffusion layer. The P type diffusion layer is formed to have an impurity concentration peak deeper than the N type diffusion layers. This structure reduces a resistance value of a base region of a parasitic transistor, suppresses an increase in an electric potential of a base region in the MOS transistor, and thereby prevents the parasitic transistor from operating. Moreover, a breakdown voltage characteristic of the MOS transistor, which might be deteriorated by the operation of the parasitic transistor, is improved.
