Abstract: PURPOSE: To improve the effect of magnetic screen by fixing the neutralized cell, which is covered with a magnetic shield of multistructure, to the vacuum container.  
     CONSTITUTION: Although an uniform external magnetic field HO is present, the inside field of neutralized cell 3 is damped by the magnetic shields 11, 12. Let the shielding factor and cross-sectional area of the external shield 11 be S 1  and A 1 , those of internal shield 12 be S 2  and A 2 , and the following holds. HO/H i =S 1 .S 2  (1-A 2 /A 1 ) Namely, when the cross-sectional area of internal shield 12 is made minimal and that of external shield 11 is made maximal, the whole shielding efficiency can be made maximal. When the size of external shield 11 is made that of the vacuum container to use it as the container, the corss-sectional area is made maximal.

Abstract: PURPOSE:To realize the high integration of a semiconductor memory device and to miniaturize the system to which the semiconductor memory device is applied by making an electrode containing metal titanium into a semiconductor substrate and forming an insulating film in the surface of the electrode with plasma oxidation applied to the electrode. CONSTITUTION:A thermal oxide film 2 is formed on a semiconductor substrate 1 at first. Next, a metal titanium thin film 3 is formed for a lower electrode by a sputtering method. Further, an insulating film 4 is formed with the surface of the metal titanium thin film 3 oxidized by a plasma oxidation method. Finally, a metal thin film is formed for an upper electrode 5 by an evaporation method and a capacitor is completed. Thus, since metal titanium is oxidized by oxygen plasma which is high density and high reactive, an insulating film containing oxide titanium of high dielectric constant can be made at a low temperature as compared with the other oxidation method such as thermal oxidation method. Thereby, the fining of of a capacitor can be performed with sufficient capacity being secured for alpha-ray resistance.
