Patent ID: 7138013

Claim:
A method of manufacturing a ceramic film, comprising steps of: forming a raw material body including a first raw material liquid and a second raw material liquid on a substrate; crystallizing a region produced from the raw material body which is one of the first raw material liquid and the second raw material liquid; crystallizing a region produced from the raw material body which is other one of the first raw material liquid and the second raw material liquid; applying the raw material body including the first raw material liquid and the second raw material liquid which has a crystallization temperature higher than a crystallization temperature of the first raw material liquid, to a substrate; annealing the raw material body at a temperature of 500 to 600° C. by rapid thermal annealing (RTA) to form microcrystal nuclei; and annealing the raw material body at a temperature of 600 to 650° C. by furnace annealing (FA) to promote crystallization.
