Abstract: A method of forming a coating film over a substrate is provided. The method includes spinning the substrate. The method further includes providing a central coating liquid spray over a central portion of the substrate. The method also includes providing first coating liquid sprays over the substrate. The first coating liquid sprays surround the central coating liquid spray and are spaced apart from the central coating liquid spray by a same first distance.
