    • PROBLEM TO BE SOLVED: To provide a technique which allows for achievement of stabilized circuit operation according to the specifications of the design and enhancement of the output current density, by suppressing variation in the channel length or the threshold voltage of an intermediate and high breakdown voltage MOSFET in an integrated circuit (semiconductor device) assuming mixed mounting of micro CMOS and intermediate and high breakdown voltage MOSFET.SOLUTION: The width (channel) of a channel region CH is decreased. More specifically, when the width of the channel region CH overlapping a gate electrode G in the plane is L, and the thickness of the gate electrode G is t, the channel region CH is formed so that the width L of the channel region CH is equal to 1/5-1 time of the thickness t of the gate electrode G. Consequently, the width L of the channel region CH can be decreased and variation in threshold voltage can be reduced.
