Abstract:
1. An apparatus for preparing a substrate, the apparatus comprising: a proximity head configured to be applied to a substrate frontside, the proximity head capable of generating a preparation meniscus on the substrate frontside, the preparation meniscus including a preparation chemistry configured to remove a material defined on the substrate frontside; and a megasonic proximity head configured to be applied to a substrate backside, the megasonic proximity head capable of generating a coupling meniscus from a fluid on the substrate backside, the megasonic proximity head further capable of imparting megasonic energy to the coupling meniscus, the megasonic proximity head including, wherein the megasonic energy imparted to the coupling meniscus is configured to enhance a mass transport of the preparation chemistry through a material to be removed on the substrate frontside.
