Abstract:
An apparatus for supplying a developing solution to a stationary substrate, comprising:a) substrate holding means for holding a stationary substrate horizontally;b) a developing solution dispensing nozzle for dispensing a developing solution onto said substrate;c) moving means for moving said developing solution dispensing nozzle over said substrate which is held still by said substrate holding means, from a position on one side off said substrate to a position on the other side off said substrate; andd) control means for controlling a quantity of a supply of said developing solution from said developing solution dispensing nozzle onto said substrate to be constant per unit area over the entire substrate while said developing solution dispensing nozzle driven by said moving means passes over said substrate, said control means comprising speed control means which sets a travel speed of said developing solution dispensing nozzle at which said developing solution dispensing nozzle moves from a predetermined position on said substrate to an edge of said substrate on the other side to a first speed, and sets a travel speed of said developing solution dispensing nozzle at which said developing solution dispensing nozzle moves from an edge of said substrate on said one side to said predetermined position to a speed which is faster than said first speed.
