Abstract:
1. An apparatus for processing a substrate, comprising: a plating head configured to plate a top surface of the substrate with a layer of a material using a fluid meniscus between the plating head and a surface of the substrate, the plating head disposed above a top surface of the substrate, wherein the fluid meniscus is delivered and removed through the plating head; and a fluid meniscus stabilizing apparatus affixed to a side surface defined around a periphery of the plating head and disposed above the top surface of the substrate, the fluid meniscus stabilizing apparatus configured to apply a pre-processing fluid to the surface of the substrate before the fluid meniscus is applied to the surface, the fluid meniscus stabilizing apparatus having a sloped top surface sloping downward from the periphery leading to an opening extending through the fluid meniscus stabilizing apparatus to the top surface of the substrate wherein the pre-processing fluid is delivered to the sloped surface through an applicator and flows to the top surface of the substrate through the opening.
