摘要：A coating solution is sprayed on a rotating wafer held horizontally from anozzle provided above the wafer while the nozzle is travelling over the wafer from a
wafer center to a wafer outer area, thus spirally spraying the coating solution on thewafer. The nozzle stops when the coating solution has reached the wafer outer area andthe coating solution is sprayed in circle on the wafer outer area while the wafer is
rotating. A coating solution including a component of a coating film and a solvent may besprayed on a first area to be coated of the wafer and the coating solution and a solventfor the coating film may be sprayed on a second edge area located outside the first areaof the wafer.
