Abstract:
1. A method for fabricating semiconductor device, comprising: forming a semiconductor layer and a first electrode of a capacitor by depositing amorphous silicon on a substrate and patterning the amorphous silicon; forming a first insulation layer on the semiconductor layer and the first electrode of the capacitor; forming source/drain regions and a channel region of the semiconductor layer by implanting impurities into the semiconductor layer and implanting impurities into the first electrode of the capacitor; forming a first insulation layer pattern on the channel region by etching the first insulation layer; forming a crystallization inducing material on the semiconductor layer and the first electrode of the capacitor that are exposed by the first insulation layer pattern; forming a second insulation layer on the crystallization inducing material; and crystallizing regions of the source/drain regions and the first electrode of the capacitor by a metal induced crystallization method and crystallizing the channel region by a metal induced lateral crystallization method by heat treating the substrate.
