Patent ID: 6991385

Claim:
An apparatus for supplying a developing solution onto a substrate, comprising: a developing solution spurting nozzle having a long shape in one direction and serving to spurt the developing solution in substantially a band shape in the longitudinal direction thereof; a developing solution supply device for supplying a developing solution having a prescribed concentration into said developing solution spurting nozzle; and a plurality of liquid supply devices for separately supplying a plurality of different kinds of liquid materials into said developing solution spurting nozzle, wherein said developing solution spurting nozzle comprises: a developing solution reservoir for storing the developing solution supplied from said developing solution supply device; a plurality of liquid reservoirs for separately storing a plurality of different kinds of liquid materials supplied from said plural liquid supply devices; a liquid mixing chamber having a liquid spurting port for spurting a developing solution or said plural kinds of liquid materials formed in the lower end and communicating with said developing solution reservoir and with said plural liquid reservoirs; a first communicating passageway for allowing said developing solution reservoir to communicate with said liquid mixing chamber; and a second communicating passageway for allowing each of said plural liquid reservoirs to communicate with said liquid mixing chamber, and wherein said developing solution and said plural different kinds of liquid materials are spurted separately from said liquid spurting port, or at least two kinds of liquid materials selected from said plural kinds of different materials are mixed in said liquid mixing chamber so as to prepare a prescribed liquid material, which is spurted from said liquid spurting port.
