Abstract:
A method for dispensing photoresist over a semiconductor wafer is provided. The method includes moving a dispensing nozzle to a predetermined position where the longitudinal axis of the dispensing nozzle aligns with the central axis of the semiconductor wafer. The method further includes dispensing a chemical liquid over the semiconductor wafer via the dispensing nozzle. The method also includes dispensing a photoresist over the semiconductor wafer that is coated with the chemical liquid via the dispensing nozzle. During the dispensing of the chemical liquid and the photoresist, the dispensing nozzle stays in the predetermined position.

Claim (Index 15):
A wafer processing system for supplying chemical liquid over a semiconductor wafer, comprising:\n a dispensing nozzle comprising:\n an outer tube having a first inlet port and a first outlet port; and \n an inner tube having a second inlet port and a second outlet port; \n a first supply line connected to the first inlet port and configured for supplying a first chemical liquid to the outer tube; and a second supply line connected to the second inlet port and configured for supplying a second chemical liquid to the inner tube; wherein the second outlet port is located farther away from a longitudinal axis of the dispensing nozzle than the first outlet port and is positioned higher than the first outlet port relative to the semiconductor wafer.
