Abstract:
1. A method for processing a substrate using a proximity head, comprising: generating a first fluid meniscus on a surface of the substrate, the first fluid meniscus being generated by applying a first fluid to a surface of the substrate and by removing the first fluid from the surface of the substrate just as the first fluid is applied; and generating a second fluid meniscus in contact with and at least partially surrounding the first fluid meniscus on the surface of the substrate, the second fluid meniscus being generated by applying a second fluid to a portion of the surface of the substrate at least partially surrounding the surface of the substrate in contact with the first fluid meniscus and by removing the second fluid from the portion of the surface of the substrate just as the second fluid is applied; wherein during a substrate processing operation the first fluid meniscus and the second fluid meniscus being defined between a processing surface of the proximity head and the surface of the substrate.
