ABSTRACT:
A multi-layered unit according to the present invention includes a support substrate formed of a silicon single crystal, a barrier layer formed of silicon oxide on the support substrate, an electrode layer, which is formed of BSCCO (bismuth strontium calcium copper oxide) having a stoichiometric composition represented by Bi2Sr2CaCu2O8, having an anisotropic property and conductivity and enabling epitaxial growth of a dielectric material containing a bismuth layer structured compound thereon and is oriented in the c axis direction, and a dielectric layer formed by epitaxially growing a dielectric material containing a bismuth layer structured compound having a composition represented by SrBi4Ti4O15on the electrode layer and oriented in the c axis direction on the electrode layer.
