Patent ID: 7517560

Claim:
A method of manufacturing a substrate having a resist film on a surface thereof comprising: resist agent coating steps of: raising liquid resist agent stored in a liquid tank by a capillary phenomenon to a top portion of a coating nozzle, orienting a surface of the substrate to be coated in a downward-facing direction, and with a separation from the top portion of the coating nozzle sufficient to having a predetermined coating gap formed between the surface and a top portion of the coating nozzle, and performing a relative scan between the coating nozzle and the surface while the resist agent raised by the coating nozzle is in contact with the surface, thereby forming a coating film, wherein the substrate is a rectangle substrate, one of sides of which has a length that is equal to or more than 300 mm; and a thickness of the coating film is set at a value selected from a range from 200 nm to 2000 nm, and the coating gap is set to be equal to or more than 200 μm, so that a film thickness distribution rate of the coating film in a region, of which area is at least 70% of area of the substrate, is equal to or less than 1%.
