摘要: The semiconductor device comprises a isolation region 14 formed in substrate 10 , lower electrode 16 12 defined by the and of an impurity diffused layer, dielectric film 18 thermal oxide on electrode, upper 20 film, insulation layer 26 substrate, covering first conductor plug 30 buried contact hole 28 down to second b being not region. is whereby short-circuit between cavity can be prevented. Thus, capacitor high reliability provided.
