  • Patent number: 8643117
    Abstract: In an SOI-MISFET that operates with low power consumption at a high speed, an element area is reduced. While a diffusion layer region of an N-conductivity type MISFET region of the SOI type MISFET and a diffusion layer region of a P-conductivity type MISFET region of the SOI type MISFET are formed as a common region, well diffusion layers that apply substrate potentials to the N-conductivity type MISFET region and the P-conductivity type MISFET region are separated from each other by an STI layer. The diffusion layer regions that are located in the N- and P-conductivity type MISFET regions) and serve as an output portion of a CMISFET are formed as a common region and directly connected by silicified metal so that the element area is reduced.
