    • A capacitor of the type having an insulative layer (8) of at least one of a ferroelectric substance and a dielectric substance having a high dielectric constant, sandwiched between a lower electrode (12) and an upper electrode (15). One or both electrodes (12,15) is made of a material of columnar crystals (6) and includes a layer of at least any one of WO x , TiO x , TaO x , IrO 2 , PtO 2 , RuO x , ReO x , PdO x and OsO x . The lower electrode (12) may be formed on an oxidation layer (4), for example a silicon oxidation layer, on a substrate (2). The lower electrode (12) may be composed by forming a conductive layer made of any one of W, Ti, Ta, Ir, Pt, Ru, Re, Pd, and Os on the oxidation layer.
    • 一种电容器,它具有夹在下电极(12)和上电极(15)之间的铁电物质和介电常数至少之一的绝缘层(8)。 一个或两个电极(12,15)由柱状晶体(6)的材料制成并且包括WOx,TiOx,TaOx,IrO2,PtO2,RuOx,ReOx,PdOx和OsOx中的至少任一种的层。 下电极(12)可以形成在衬底(2)上的氧化层(4)上,例如硅氧化层上。 下电极(12)可以通过在氧化层上形成由W,Ti,Ta,Ir,Pt,Ru,Re,Pd和Os中的任何一种制成的导电层来构成。
