<p>In the capacitor, electrode, or wiring having alpha ray emitting source (in particular, Pt electrode), a layer (alpha ray shielding layer) (18), which has at least one type selected from the group of nickel, cobalt, copper, and tungsten, their compounds or alloys made of at least two types of them, and compounds and alloys made of them and silicon is provided. It is possible to shield off the alpha ray effectively, to suppress generation of soft errors, to enable use of Pt and other new materials in making the electrodes and wiring, and to reduce the cost of the mold resin. <IMAGE></p> |
