摘要： Using a gate electrode formed on a semiconductor film as a mask, impurity ions are implanted into the semiconductor film. Thereafter, a photoresist film is formed on the substrate including the gate electrode. The photoresist film on the gate electrode is then exposed to light from a back side of the gate electrode. By this self-alignment method, a resist pattern narrower than the gate electrode is formed. Then, the gate electrode is narrowed through the etching thereof using the photoresist pattern as a mask, whereby an offset gate structure of a thin-film transistor is obtained.
