Abstract
A method of manufacturing a semiconductor device includes process of introducing a material for promoting crystallization of an amorphous semiconductor film, crystallizing the amorphous semiconductor film to form a crystalline semiconductor film, introducing phosphorus to form a source region, a drain region, a pair of light doped regions and a channel region being defined between the pair of the light doped region, heating the crystalline semiconductor film so that the material is diffused from the channel region to each of the source and drain regions through each of the pair of light doped region.
