Semiconductor integrated circuit and method for manufacturing the same

A semiconductor integrated circuit according to the present invention comprises a MOS transistor formed on an SOI substrate and a subsidiary transistor provided between a body node and a drain node of the MOS transistor and sharing a gate electrode with the MOS transistor, whereby body potential of the MOS transistor is controlled by gate and drain potentials. Accumulated body charge in a non-conducting state in the semiconductor integrated circuit is extracted by a resistor formed between the body node and a source, whereby various phenomena caused by floating body effect are eliminated. Since the body potential of the MOS transistor can be varied without creating an undesirable leakage current path, and hence without limitations to supplied voltage, its threshold voltage can be made variable so as to follow change in an input signal, thereby making it possible to achieve higher speed and lower voltage operation of the semiconductor integrated circuit. According to the present invention, it is possible to eliminate floating body effect, which is the greatest problem with an SOI transistor formed on an SOI substrate, and also to achieve lower voltage and greater current operation of a transistor without posing limitations to supplied voltage and without causing the problem of leakage current.
