Abstract:
A semiconductor element comprising:a semiconductor section carrying a transistor formed therein; anda capacitor section having a capacitor,wherein the capacitor includes epitaxially grown first and second electrodes, and an epitaxially grown dielectric film is arranged between the first and second electrodes,also wherein the transistor and the capacitor form a memory cell, a first electrode and a second electrode are sequentially stacked above a monocrystalline substrate to produce a multilayer structure, the transistor is formed on the capacitor with an insulation layer interposed therebetween, and either a source or a drain of the transistor is connected to the second electrode by way of a contact hole formed through the insulation layer,further wherein the first electrode is made of an electroconductive material having a crystal structure with a tetragonal system type (100)-plane and the dielectric film has a tetragonal system type perovskite crystal structure.
