Abstract:
1. A system for cleaning a substrate, the system comprising: a first head configured as a bar shape that extends approximately a diameter of the substrate, the first head configured for placement on a first side of the substrate; a second head configured as a bar shape that extends approximately the diameter of the wafer, the second head configured for placement on a second side of the substrate, the second side is opposite the first side; each of the first head and the second head having conduits formed therein for delivering and removing fluids so that a meniscus is capable of being contained between each of the first head and a substrate surface of the first side of the substrate and the second head and a substrate surface of the second side of the substrate, the first head and the second head having head surfaces that include substantially flat surface regions and discrete holes for defining the conduits, the discrete holes extending through the head surfaces of the first head and the second head.
