Abstract:
1. A substrate treating apparatus comprising: a substrate holding mechanism which holds a substrate, the substrate including a plurality of chips; a solution discharge/suction unit including a solution discharge port for discharging a first solution to one of the chips included in the substrate, and a circle-like suction port for sucking the first solution on the substrate, the suction port being disposed to surround continuously the periphery of the solution discharge port; a moving mechanism which removes the substrate and the solution discharge/suction unit relatively; a solution discharge/suction system which simultaneously performs supplying the first solution to the solution discharge/suction unit and sucking the first solution from the solution discharge/suction unit; a covering rate calculating unit which calculates the covering rate of a pattern included in each of the chips treated by a first solution in a treating region where the first solution flow exists on the substrate; and a control unit which controls the moving mechanism based on the pattern covering rate calculated by the covering rate calculating unit.
