Abstract:
1. A method of fabricating a thin film transistor using a super grain silicon (SGS) crystallization process, the method comprising: forming an amorphous silicon film having a zigzag shape on an insulating substrate; forming a gate insulating film on the amorphous silicon film and the insulating substrate; forming a gate electrode on the gate insulating film so that the gate electrode overlaps the amorphous silicon film; forming an interlayer insulating film on the gate electrode and the gate insulating film; forming contact holes through the interlayer insulating film and the gate electrode film exposing portions of the amorphous silicon layer near edges of two sides of the amorphous silicon film; forming a capping layer contacting the exposed portions of the amorphous silicon film through the contact holes; forming a metal film on the capping layer; and forming a semiconductor layer comprising a polycrystalline silicon film by crystallizing the amorphous silicon film using the SGS crystallization process.
