Abstract:
To allow a metal oxide film composed mainly of O and at least one of Hf and Zr to exhibit ferroelectric properties. After deposition of a hafnium oxide film on a semiconductor substrate via an insulating film, the semiconductor substrate is exposed to microwaves to selectively heat the hafnium oxide film. This makes it possible to form a larger number of orthorhombic crystals in the crystals of the hafnium oxide film. The hafnium oxide film thus obtained can therefore exhibit ferroelectric properties without adding, thereto, an impurity such as Si. This means that the hafnium oxide film having a reverse size effect can be used as a ferroelectric film of a ferroelectric memory cell and contributes to the manufacture of a miniaturized ferroelectric memory cell.

Claim (Index 15):
The method of manufacturing a semiconductor device according to  claim 14 ,\n wherein the second conductor film is deposited by RF sputtering.
