Abstract: A vacuum chuck and an inner cup are rotated together by a spinner for spreading and coating a coating solution uniformly on a glass substrate in the inner cup under centrifugal forces. Under the centrifugal forces, gases that are present inward of a rectangular ridge in the inner cup are forced to flow outwardly through a gap between the rectangular ridge and a flow-rectifying plate 42 and also through holes defined in the rectangular ridge. Therefore, turbulent flows and pressure fluctuations are minimized in a space defined inward of the rectangular ridge, i.e., a space which accommodates the glass substrate placed on a bottom surface of the inner cup inwardly of the rectangular ridge. The coating solution applied to the upper surface of the glass substrate is allowed to form a uniform film thereon.
