The invention provides a semiconductor device and a method of fabricating the same. A threshold voltage adjustment ion implantation is performed on each of the transistor regions by a full ion implantation process to form a threshold voltage adjustment layer, threshold voltages and leakage currents of the formed transistors are adjusted, an ion implantation step primarily requiring mask of the gate polysilicon can be omitted at the same time, and a first well structure having a first conductivity type may be employed instead of the common well structure of the first conductivity type in transistor regions such as a low voltage PMOS transistor region of the semiconductor substrate to eliminate the process of forming a common well structure of the first conductivity type in the low voltage PMOS transistor formed by using the mask, thereby saving two photolithographic masks, improving resource waste and simplifying the process.
