Abstract: PURPOSE:To make it possible to restrain operation errors or damages of data caused by injected electrons in an internal circuit or a memory cell by surrounding a diffusion layer of a capacitor with a diffusion layer of a substrate potential without making a substrate potential shallow. CONSTITUTION:When a potential of a substrate 15 is higher than that of a diffusion layer and a channel part 11 of a capacitor and a threshold voltage VT1 of a first MOS field effect transistor, an N-P-N parasitic bipolar transistor is formed between the substrate and a peripheral diffusion layer 16 which is electrically connected to a substrate potential (SP). However, electrons injected into the substrate 15 from the diffusion layer and the channel part 11 of the capacitor reach the peripheral diffusion layer 16 electrically connected with the substrate 15, so that there is no bad influence upon the generation of a substrate potential. Furthermore, as the peripheral diffusion layer 16 of substrate potential surrounds the diffusion layer and the channel part 11 of the capacitor, the electrons injected in the substrate 15 do not reach an internal circuit or a memory cell and the prevention of the damages of data becomes possible.
