Abstract

PURPOSE: To accelerate the operating speed of a semiconductor device by decreasing the resistance thereof without increasing the thickness of a polycrystal silicon layer doped with impurities in the device by illuminating laser light through an insulating layer to the silicon layer when forming an electrode or wire using the silicon layer.
CONSTITUTION: Thick field SiO2 films 12 are formed on both ends of a p-type silicon substrate 11, and a thin gate SiO2 film 13 is coated on the surface of the substrate 11 surrounded by the film 12 to then a polycrystal silicon layer 14 is grown on the entire surface in vapor. N-type impurities are doped with the layer 14 to impart a conductivity to the layer 14. Then, a mask 15 of photoresist film is provided, and etched to thereby retain only a layer 14' becoming a gate electrode or a wire. Then, the mask 14 is removed, N-type source and drain regions 16 and 17 are formed by an ion implantation process with the layer 14' as a mask, a PSG film 18 is coated on the entire surface, and heat treated to thereby form a smooth surface by means of reflow. Then, laser light 30 is illuminated through the film 18 to the layer 14' to thereby lower the resistance to predetermined value, and openings are provided to mount aluminum layers 19a and 19b making contact with the regions 16 and 17.
