Abstract:
1. A method of manufacturing a CMOS thin film transitor, comprising: forming an amorphous silicon layer having a zigzag shape on an insulating substrate, the amorphous silicon layer having a PMOS transistor region and an NMOS transistor; forming a gate insulating layer over the entire surface of the substrate; forming a gate electrode having at least one slot crossing the amorphous silicon layer on the gate insulating layer; forming an interlayer insulating layer over the entire surface of the substrate having a contact hole exposing both edges of the PMOS transistor region and the NMOS transistor region; forming a metal layer to contact the exposed portion of the amorphous silicon layer via the contact hole; crystallizing the amorphous silicon layer using an MILC to form a poly silicon layer, thereby forming a semiconductor layer; and forming source and drain electrodes contacting the semiconductor layer via the contact hole.
