Abstract: PROBLEM TO BE SOLVED: To solve the problem that conventionally semiconductor devices, such as those for the implantation defect being caused by the doping treatment for leading in the impurity elements for gettering the metallic elements used for acceleration of crystallization and the impurity elements for giving P-type occurs in a semiconductor layer to form a p-channel type TFT, and that it exerts adverse influence on the electrical properties at manufacture of a TFT. SOLUTION: Accelerating voltage at doping treatment has a large influence on implantation defects. To reduce the above implantation defects, it is to be desired that the above acceleration voltage be even lower still. For its sake, the doping treatment is performed separately in two times by changing its accelerating voltage, when forming a low concentration impurity diffusion region and a high concentration diffusion region existing under the tapered section of a gate electrode. By so doing, the implantation defects in the semiconductor film can be minimized. Furthermore, the flexibility in design is improved, because the quantity of introduction of impurity elements can be changed for the above heavily-doped region and the lightly-doped region.
