Abstract:
The present invention provides a semiconductor device including SRAM cell units each including a data holding section made up of a pair of driving transistors and a pair of load transistors, a data write section made up of a pair of access transistors, and a data read section made up of an access transistor and a driving transistor, wherein each of the transistors includes a semiconductor layer projecting upward from a base plane, a gate electrode extending from a top to opposite side surfaces of the semiconductor layer so as to stride the semiconductor layer, a gate insulating film between the gate electrode and the semiconductor layer, and source/drain areas, a longitudinal direction of each of the semiconductor layers is provided along a first direction, and for all the corresponding transistors between the SRAM cell units adjacent to each other in the first direction, the semiconductor layer in one of the corresponding transistors is located on a center line of the semiconductor layer along the first direction in the other transistor.
