Abstract
A close a-axis orientating film having a smooth surface and excellent ferroelectric characteristics is manufactured at a low temperature with preferable reproducibility to apply ferroelectric Bi.sub.4 Ti.sub.3 O.sub.12 to development of various kinds of devices such as a ferroelectric non-volatile memory, a pyroelectric sensor, etc. A ferroelectric Bi.sub.4 Ti.sub.3 O.sub.12 thin film is formed on a substrate through a titanium oxide buffer layer so that closeness and surface smoothness of the Bi.sub.4 Ti.sub.3 O.sub.12 thin film manufactured on the titanium oxide buffer layer can be improved.
