摘要:
A lower electrode is formed over a substrate, and a raw material including a complex oxide is heated in an atmosphere pressurized to two atmospheres or more and containing oxygen at a volume ratio of 10% or less at a temperature raising rate of 100° C./min or less, thereby forming a lower alloy film of a compound of a first metal which makes up the complex oxide, and a second metal, which makes up the lower electrode, over the lower electrode. A ceramic film in which the raw material is crystallized is formed over the lower alloy film, and an upper electrode is formed over the ceramic film.

A ferroelectric memory device of the present invention includes a memory cell array in which memory cells are arranged in a matrix having first signal electrodes, second signal electrodes arranged in a direction intersecting the first signal electrodes, and a ferroelectric layer disposed at least in intersection regions between the first signal electrodes and the second signal electrodes, and a peripheral circuit section for selectively writing information into or reading information from the memory cell. The memory cell array and the peripheral circuit section are formed in different layers. The peripheral circuit section is formed in a region outside the memory cell array.
摘要:
A method of manufacturing a ferroelectric capacitor. In this method, a lower electrode is formed on a base at first. A ferroelectric film which includes a PZTN complex oxide including lead, zirconium, titanium, and niobium on the lower electrode is formed, and then an upper electrode is formed on the ferroelectric film. A protective film is then formed to cover the lower electrode, the ferroelectric film, and the upper electrode, and heat treatment for crystallizing the PZTN complex oxide is performed at least after forming the protective film.
