Process for producing oriented inorganic crystalline film, and semiconductor device using the oriented inorganic crystalline film
First Claim
1. A process for producing an oriented inorganic crystalline film, comprising the steps of:
- (A) forming on a substrate a non-monocrystalline film containing inorganic crystalline particles by a liquid phase technique using a raw-material solution which contains a raw material and an organic solvent, wherein the raw material contains the inorganic crystalline particles and the inorganic crystalline particles have a layered crystal; and
(B) crystallizing said non-monocrystalline film by heating the non-monocrystalline film to a temperature equal to or higher than a crystallization temperature of the non-monocrystalline film so that part of the inorganic crystalline particles act as crystal nuclei.

Abstract
In a process for producing an oriented inorganic crystalline film, a non-monocrystalline film containing inorganic crystalline particles is formed on a substrate by a liquid phase technique using a raw-material solution which contains a raw material and an organic solvent, where the inorganic crystalline particles have a layered crystal structure and are contained in the raw material. Then, the non-monocrystalline film is crystallized by heating the non-monocrystalline film to a temperature equal to or higher than the crystallization temperature of the non-monocrystalline film so that part of the inorganic crystalline particles act as crystal nuclei.
