发明名称 Thin film transistor device and method of manufacturing the same
摘要 A polysilicon film is formed in a predetermined region on a glass substrate, and then a gate insulating film and a gate electrode, whose width is narrower than the gate insulating film, are formed thereon. Then, an interlayer insulating film and an ITO film are formed on an overall surface. Then, n-type source/drain regions having an LDD structure are formed by implanting the n-type impurity into the polysilicon film. Then, an n-type TFT forming region and a pixel-electrode forming region are covered with a resist film, and then p-type source/drain regions are formed by implanting the p-type impurity into the polysilicon film in a p-type TFT forming region. Then, the resist film is left only in the pixel-electrode forming region and the resist film is removed from other regions. A pixel electrode is formed by etching the ITO film while using the remaining resist film as a mask.
