Abstract
A perovskite crystallized ferroelectric substance is formed over a lower electrode. A precursor solution, which serves as a ferroelectric film, is applied thereto and dried, followed by low-temperature anneal under the condition of a perovskite crystallization temperature or lower. Further, an upper electrode is formed and thereafter subjected to high-temperature anneal at a temperature of the perovskite crystallization temperature or higher to thereby perfectly crystallize the ferroelectric film, whereby a semiconductor element interposed between the electrodes can be formed.
