Claim 5:
6. A substrate processing apparatus for removing an organic film on a substrate, the substrate processing apparatus comprising:
a substrate processing chamber;
a substrate holder configured to hold said substrate in said substrate processing chamber;
an ozone supplier configured to supply ozone-containing gas into said substrate processing chamber;
an atomization nozzle configured to spray a chemical liquid containing sulfuric acid onto said substrate;
a chemical liquid supplier including a heater and configured to supply said chemical liquid heated by said heater to said atomization nozzle; and
a controller configured to control said ozone supplier to fill at least a space above said substrate in said substrate processing chamber with ozone-containing gas, and then control said chemical liquid supplier to start spraying said chemical liquid through said space onto said substrate so that said substrate is processed by said chemical liquid that has been reacted with said ozone in said space, wherein
said atomization nozzle is arranged to face an upper surface of said substrate.
