Abstract

PURPOSE:To eliminate the distortion of VD-ID curve by a method wherein a gate electrode is formed on a semiconductor layer through an insulation layer, and N<+> layers are formed in parallel isolated from each other on a clean surface of the semiconductor layer. CONSTITUTION:An a-Si-TFT is formed on a substrate 106 made of glass, ceramics or the like by laminating in sequence a gate electrode 101, an electrical insulation layer 104 designed to cover the gate electrode 101 and a semiconductor layer 105 composed of hydrided and/or fluorided amorphous silicon, and constructed to have a structure in which the first N<+> layer 107-1, the second N<+> layer 107-2 are mounted isolated from each other in a parallel relation on the surface 108 of the semiconductor layer 105, and in addition, a source electrode 102 is mounted on the first N<+> layer 107-1 and a drain electrode 103 on the second N<+> layer 107-2, respectively. The N<+> layers are formed during the surface 108 of the semiconductor 105 being in the clean state just after the formation of the layer, thereby a satisfactory ohmic contact is formed on the interface of the semiconductor layer 105 and the N<+> layers 107.
