Patent ID: 7069937

Claim:
A substrate preparation apparatus to be used in substrate processing operations, comprising: an arm capable of vertical movement between a first edge of the substrate to a second edge of the substrate; a holder for holding the substrate in a vertical orientation; and a head coupled to the arm, the head being capable of forming a fluid meniscus on a surface of the substrate and capable of being moved over the surface of the substrate, and wherein the meniscus is defined on the substrate when in the vertical orientation; and wherein the head includes, at least one of a first source inlet for delivering a first fluid to the surface of the substrate through the head; at least one of a second source inlet for delivering a second fluid to the surface of the substrate through the head, the second fluid being different than the first fluid; and at least one of a source outlet for removing each of the first fluid and the second fluid from the surface of the substrate, the at least one of the source outlet being located to substantially surround the at least one of the first source inlet, and the at least one of the first source inlet, the at least one of the second source inlet, and the at least one of the source outlet being configured to act substantially simultaneously when in operation; wherein the at least one of the second source inlet surrounds at least a trailing edge side of the at least one of the source outlet.
