Arsenic ions as impurities are further implanted. Thereafter, annealing is performed at 600 deg.C in a nitrogen atmosphere for 12 hours. Thus, the film 13 is transformed into the polysilicon 14. Then, the polysilicon resistor is formed by using a lithography technology. Then a CVD silicon oxide film 15 as a cover and a metal 16 for providing conductivity with the polysilicon are further formed.
