Classification: CPC B  G  H | IPC B

Claim 0:
1. A coating method, comprising:
supplying a film forming liquid onto a front surface of a substrate from a nozzle in a state that a distance between the front surface of the substrate and a lower end of the nozzle is maintained at a coating distance; and
diffusing the film forming liquid supplied from the nozzle toward an edge of the substrate by rotating the substrate,
wherein the coating distance is larger than a thickness of an outer periphery region of a film of the film forming liquid, the outer periphery region is a region other than directly below the lower end of the nozzle,
wherein the coating distance is set to allow the film forming liquid to stay between a lower end surface of the nozzle and the front surface of the substrate in a state that both the lower end surface of the nozzle and the front surface of the substrate are in contact with the film forming liquid when a discharge of the film forming liquid from the nozzle is stopped.
