A coating apparatus is provided in which a coating liquid supplied onto a
surface of a substrate such as a semiconductor wafer and a glass
substrate can be easily leveled so as to have a uniform thickness without
any edge bead. The coating apparatus comprises a tray, a nozzle for
supplying a coating liquid, and a squeegee which serves as an applicator
for spreading a coating liquid. The tray has a recessed portion into
which a substrate is placed, and a spinner chuck is provided in the
recessed portion. In the spinner chuck, a chuck for attracting the
substrate is attached to the upper end of a spinner shaft which can be
lifted and lowered, and the upper surface of the chuck and the bottom
surface of the recessed portion are arranged to be in the same plane in a
state where the spinner shaft is lowered to the lowest position.
