Layer crystal structure oxide, production method thereof, and memory element using the same
First Claim
1. A production method of a crystal structure oxide comprising the steps of evaporating a material by heating to generate a gas phase, precipitating a crystal from the gas phase at a precipitating part so as to produce a layer crystal structure oxide, wherein the precipitating part is spaced apart from the material by a distance ranging from greater than or equal to about 10 mm to about 30 mm or less.

Abstract
A production method of a crystal structure oxide that includes the steps of evaporating the material by heating the material to generate a gas phase and precipitating crystals from the gas phase at a precipitating part so as to produce a layer crystal structure oxide. The precipitating part is provided away from the material in a range of greater than or equal to about 10 mm to about 30 mm.
