Patent ID: 7328713

Claim:
A nozzle apparatus for stripping an edge bead of a wafer, comprising: a support arm capable of being rotated about an axis and vertically raised and lowered; a side rinse nozzle coupled to a leading end of the support arm, wherein the side rinse nozzle is configured to remove a bead of photoresist on the edge of the wafer, wherein the side rinse nozzle comprises a first nozzle configured to remove a bead on an upper surface of the wafer edge, and; a second nozzle configured to remove a bead on an outer end surface of the wafer, and wherein the first and second nozzles each have an elongated length in a radial direction of the wafer and a narrow width; wherein the first nozzle is configured to have a spray angle such that a cleaning solution sprayed from the first nozzle is sprayed from inside to outside of the wafer at an upper portion of the wafer edge, and wherein the second nozzle is configured to have a spray angle such that a cleaning solution sprayed from the second nozzle is sprayed inwards from outside of the wafer edge; and wherein the first and second nozzles have respective tips, each with a length that is prolonged in a radial direction of the wafer.
