Abstract:
A coating processing apparatus for coating a coating solution onto the surface of a substrate, comprising:a rotating cup having an opening portion on the top thereof and housing the substrate; a drain cup surround the rotating cup; rotating means for rotating the rotating cup; a spin chuck for holding and rotating the substrate in the rotating cup; a lid body having an opening and attached to said rotating cup for closing the opening portion, said lid body defining a processing space between the lid body and the substrate on the spin chuck; a coating solution discharge nozzle for discharging the coating solution onto the substrate held on the spin chuck through the opening of said lid body; a small lid attached to said lid body for blocking up the opening of said lid body; and a protrusion member placed on a lower part of said small lid such that the protrusion member faces the substrate on the spin chuck for generating an airflow in the processing space which flows along the substrate from a center to a periphery of the processing space while the substrate is rotated by the spin chuck and the rotating cup is rotated by the rotating means.
