In a thin film transistor, a metallic element promoting crystallization of an amorphous silicon film is effectively removed and the productivity is improved. By using a silicon film containing an element belonging to the group 15 such as phosphorus through contact holes reaching a source region and a drain region, a metallic element promoting crystallization of an amorphous silicon film can be effectively removed or decreased and the productivity can be improved.
