Abstract: PURPOSE:To enhance a semiconductor element in performance by a method wherein a silicon provided with fine irregularities of grains on its surface is made to serve as an electrode, and a silicon film large in surface area is deposited at a transition temperature where the crystal of the deposited film is changed into a polycrystal state from an amorphous state. CONSTITUTION:Phosphorus is diffused to a silicon film 54 deposited at a temperature of 820 deg.C for 60 minutes on an Si substrate 50 where a thick SiO2 film 52 has been formed, then a capacitor insulating film 16 is formed on the film 54, and a polysilicon film 58 serving as an upper electrode is formed thereon. The formation of the film 56 is carried out in such a manner that an Si3N4 film is formed on a silicon film, and the surface of the film concerned is thermally treated at a prescribed temperature using a prescribed gas to form a stacked capacitor as shown in the figure. Very fine irregularities can be induced easier on the surface of a deposited silicon film when a silicon film is deposited at a transition temperature where the crystal of the deposited silicon layer is changed from an amorphous state to a polycrystal state as compared with a case in which the silicon layer is deposited at a temperature other than the transition temperature concerned, so that the film concerned is increased in surface area. By this setup, a semiconductor element can be lessened in dispersion of leakage current characteristics and breakdown strength.
