ABSTRACT:
An object of the present invention is to realize a semiconductor device having a high TFT characteristic. In manufacturing an active matrix display device, electric resistivity of the electrode material is kept low by preventing penetration of oxygen ion into the electrode in doping of an impurity ion. A display device having a low electric resistivity can be obtained.
