In a semiconductor integrated circuit device having a system-on-chip structure in which a DRAM and a logic integrated circuit are mixedly mounted on a chip, a silicide layer is formed on the surfaces of the source and the drain of a MISFET of a direct peripheral circuit of the DRAM, the surfaces of the source and the drain of a MISFET of an indirect peripheral circuit of the DRAM, and the surfaces of the source and the drain of a MISFET of the logic integrated circuit, and the silicide layer is not formed on the surfaces of the source and the drain of a memory cell selective MISFET of the memory cell of the DRAM. |
