This invention provides a semiconductor device and its fabrication method, comprising the following steps: providing a substrate; forming a carbon nanotube layer on the substrate, the carbon nanotube layer having at least one carbon nanotube; forming a defect structure in contact with the carbon nanotube layer, the defect structure containing charged defects, the charged defects acting on the carbon nanotube layer to electrically dope the carbon nanotube layer; wherein, the electrical doping concentration of the carbon nanotubes is controlled by adjusting the density of the charged defects. In this invention, electrical doping of the carbon nanotube layer through the defect structure only changes the electrical properties of the carbon nanotube layer without damaging its physical structure, achieving non-destructive electrical doping. Furthermore, using a high work function metal layer as the source and drain electrodes of the N-type carbon nanotube device simplifies the design rules of carbon nanotube integrated circuits, facilitates the large-scale integrated circuit application of carbon nanotube devices, and enables the matching of N-type and P-type devices.
