Abstract
A semiconductor integrated circuit device includes a silicon substrate having a first region and a second region identical in conductivity type to the first region and having a lower dopant concentration than the first region, a second MOS transistor on a main surface of the second region as a radio frequency switch circuit switching on and off input and output of a radio frequency signal, and a first MOS transistor on a main surface of the first region in a radio frequency circuit other than the radio frequency switch circuit. A high performance, highly reliable semiconductor integrated circuit with an RE switch circuit provided on a silicon substrate as a system on a chip.
