Abstract:
1. A process of manufacturing a thin-film transistor, comprising steps of: (1) forming an amorphous silicon layer at the upper part of an unannealed glass substrate; (2) implanting an element belonging to Group IIIb or an element belonging to Group Vb, into the amorphous silicon layer; (3) irradiating the amorphous silicon layer by laser light to form a polycrystalline silicon layer; (4) forming an insulating layer on the polycrystalline silicon layer at a temperature of 500° C. or below; (5) forming a gate region on the insulating layer; and (6) implanting an element belonging to Group Vb or an element belonging to Group IIb, into a source region and a drain region by ion implantation, using the gate region as a mask.
