Abstract
A semiconductor device includes a flip-flop circuit formed in a CMOS semiconductor integrated circuit. The flip-flop circuit includes at least a first clock generating inverter that generates a first clock signal and a second clock generating inverter that generates a second clock signal obtained by inverting the first clock signal, the first clock generating inverter and the second clock generating inverter are arranged so as to sandwich a latch unit, the latch unit including a master latch unit and a slave latch unit in the flip-flop circuit, the first clock generating inverter and a first other circuit in the flip-flop circuit are configured to share a source region, the first other circuit being adjacent to the first clock generating inverter, and the second clock generating inverter and a second other circuit in the flip-flop circuit are configured to share a source region, the second other circuit being adjacent to the second clock generating inverter.
