ABSTRACT:
A semiconductor integrated circuit has a first substrate of a first polarity to which a first substrate potential is given, a second substrate of the first polarity to which a second substrate potential different from the first substrate potential is given, and a third substrate of a second polarity different from the first polarity. The first substrate is insulated from a power source or ground to which a source of a MOSFET formed on the substrate is connected. The third substrate is disposed between the first and second substrates in adjacent relation to the first and second substrates. A circuit element is formed on the third substrate.
