Patent ID: 8591991

Claim:
A fabrication method for fabricating a metal oxide thin film, comprising: introducing H 2 gas and O 2 gas, or H 2 O 2 gas, into a catalytic reactor to make contact with a catalyst, to thereby generate high-temperature H 2 O gas by combusting the H 2 gas and the O 2 gas, or the H 2 O 2 gas, in the catalytic reactor; and jetting the high-temperature H 2 O gas from the catalytic reactor to react with a metal compound gas in front of a substrate surface, to thereby generate a metal oxide gas and deposit a metal oxide thin film on the substrate surface by the metal oxide gas, wherein the catalyst includes a carrier with a catalyst component, wherein the carrier is in the form of microparticles having an average particle diameter of 0.05 mm to 2.0 mm, wherein the catalyst component consists of platinum particles carried on the carrier, and wherein the platinum particles have an average particle diameter of 1 nm to 10 nm.
